Which of the following is true concerning hurricanes?
a. They tend to deposit more sediment than they remove.
b. Their storm surges cause widespread flooding.
c. They have fast, but generally weak wind gusts.
d. They do not alter landscapes significantly.
Answer:
B.
Explanation:
B. is correct because every time usually when a hurricane hits it causes flooding causing multiple homes to be ruined. It is a known fact that usually hurricanes start close or in along with tornadoes, the water, meaning once they hit land they have some water to flood that land with.
C. is absolutely false hurricanes have VERY strong wind gusts.
D. is absolutely wrong they do alter landscapes by ripping trees and plants and houses out of the ground making the landscapes look different.
A. is wrong they tend to deposit and remove sediment evenly.

A mountain climber increases their height from 200 meters to 400 meters. What affect will this have on their potential energy?
Answer:
At 400 m the potential energy of the mountain climber doubled the initial value.
Explanation:
Given;
initial height of the mountain climber = 200 m
final height of the mountain climber, = 400 m
The potential energy of the mountain climber is calculated as;
Potential energy, P.E = mgh
At 200 m, P.E₁ = mg x 200 = 200mg
At 400 m, P.E₂ = mg x 400 = 400mg
Then, at 400 m, P.E₂ = 2 x 200mg = 2 x P.E₁
Therefore, at 400 m the potential energy of the mountain climber doubled the initial value.

Alisa, a skateboarder, is riding down a hill. If Alisa and the skateboard are considered a single object, what forces are acting on her? Check all that apply.
Answer: gravity
normal force
friction
Explanation:
A force is refered to as the interaction which when unopposed, will lead to a change in an objects motion. The velocity of an object will be changed when force is applied.
Since Alisa s riding down a hill and she and the skateboard are considered to be a single object, then the forces that are acting on her include gravity, normal force and friction.

Can someone help me find the which direction is north and which is south on this solenoid?
Explanation:
Now, looking down the solenoid tube determine what direction is the winding. If clockwise in relation to the positive wire then is the south pole, if anti-clockwise then is the north pole. So, to summarize the magnetic south pole is always clockwise in relation to the positive wire.

The displacement ‘s' of a point moving in a straight line is given by: s = 6t^2 + 5t – 5, ‘s' being in cm and ‘t' in s. The initial velocity of the particle is:
Answer:
the initial velocity of the particle is 5 cm/s
Explanation:
Given initial displacement as, s = 6t² + 5t - 5
s is measured in "cm"
t is measured in "seconds"
Velocity is the rate of change of displacement with time. Expressed as follows;
[tex]v = \frac{ds}{dt} = 12t + 5[/tex]
for initial velocity, time (t) = 0
v = 12(0) + 5
v = 5 cm/s
Therefore, the initial velocity of the particle is 5 cm/s

What happens to the apparent wavelength in the doppler effect example as the wave source moves forward, towards you?
Answer:
The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases

Three balls with different masses are shown below.
(picture of beach ball) - 85g
(picture of football) 425g
(picture of baseball) - 149g
If the same amount of kicking force is applied to each ball, which will travel the farthest?
F - They will all travel the same distance because the applied force is the same
G - the baseball because it's the smallest
H - The football because it has the highest mass and was designed for kicking
J - the beach ball because it has the lowest mass
(btw it's a football, not soccer ball)
Answer:
$10 a g
Explanation:
Answer:
As The mass of the beach ball is having lowest magnitude when compared with the other balls given so when apply the same magnitude of force to all the balls then the beach ball due to its lighternessand also its inertia of rest would not resist the force so much so when you apply the force to this ball it would starts to roll and covers the maximum diatance whwn compared with the other ball only in the condition when same magnitude of force applied.Thats this ball would do more work than the other ball.The mass also influences the velocity carried by the body and also the kinetic energy possessed by the body. More the force applied more the distance it would cover

Matthew was bowling. He bowled with a 12 pound ball at first then used a 10 pound ball. If matthew uses the same amount of force to roll the bowling balls, which one would roll faster?
F- the 12 pound ball
G - they would roll the exact same speed
H - the 10 pound ball
J - none of the above
Answer:
Rotational inertia depends both on an object's mass and how the mass is distributed relative to the axis of rotation. ... We can't just consider the mass to be concentrated at its center of mass. When a mass moves further from the axis of rotation it becomes more difficult to change the rotational velocity of the system.So the ball with 10 pounds of the ball can have more probability to do an absolute pure rotation along rolling translation.And also the specific material from which it is made up of. As If the body is rigid have the points dont move from their position when a magnitude of force applied then the body woukd perform a well rotation than a resistantant body.

If the current in the circuit is 10.5 A,
what is the potential difference across the
source?
(AI 0.750 V
(B) 9.19 V
(C) 12.0 V
(D) 49.0 V
(E) 147 V
Answer:
E) 147 V
Explanation:
Ra+Rb+Rc = 14.0
V = IR
V = (10.5)(14.0)
V = 147 V
The potential difference across the source will be c)12V
What is Ohm's law ?Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points .
since , R(A) , R(B) AND R(C) are in parallel combination , hence equivalent
resistance of the circuit will be
1/R = 1/R(A) + 1/ R(B) + 1/ R(C)
1/R= 1/2 + 1/4 +1/8
1/R = 7/8
R = 8/7 ohm
from ohm's law
Voltage = current * resistance
V( source ) = current (in circuit ) * R (equivalent resistance)
V = 10.5 * (8/7)
V = 12 V
The potential difference across the source will be c) 12V

What is the time it takes a tow truck to pull a car if it has 1,850,000J of work and 370,000 Watts of power ?
P = W / t
370,000 = 1,850,000 / t
t = 1,850,000 / 370,000
t = 185 / 37
t = 5 seconds
explain why temperature first increases, then begins to decrease throughout the day
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
A loaded spring launches a 2.50 kg block, using a force of 450 N. If the change in
momentum is 12.0 kg*m/s, how long was the block in contact with the spring?
Answer:
37.5 seconds
Explanation:
The given parameters are;
The mass of the block on the spring, m = 2.50 kg
The force with which the loaded spring launches the block, F = 450 N
The change in momentum of the block, Δp = 12.0 kg·m/s
We have;
Let the force with which the block was launched = The net force, [tex]F_{NET}[/tex]
By Newton's second law of motion, we have;
F = [tex]F_{NET}[/tex] = Δp × Δt
Where;
Δt = The time the block is in contact with the spring
Therefore;
[tex]\Delta t = \dfrac{F_{NET}}{\Delta p}[/tex]
By plugging in the values for [tex]F_{NET}[/tex] and Δp, we have;
[tex]\Delta t = \dfrac{450 \ N}{12.0 \ kg \cdot m/s} = 37.5 \ s[/tex]
The time duration the block is in contact with the spring, Δt = 37.5 seconds.
La corriente en un circuito se triplica conectando una R1 = 500 Ω en paralelo con la resistencia R del circuito. Determinar R en ausencia de R1
Answer:
R = 1000 ohm
Explanation:
In a circuit with a resistor R, the current is
V = i R
i₀ = V / R
a resistor R₁ is placed in parallel and the current is tripled i = 3 i₀
V = i Req
i = V / Req
3i₀ = V / Req
we substitute
3 (V / R) = V / Req
3 / R = 1 / Req
R = 3 Req
the equivalent resistance of the two resistors in parallel is
[tex]\frac{1}{R_{eq}} = \frac{1}{R} + \frac{1}{R_1}[/tex][tex]\frac{1}{R_{eq}} = \frac{R_1 + R}{R \ R_1}[/tex]
R_{eq} = [tex]\frac{R \ R_1}{R + R_1}[/tex]
R / 3 = \frac{R \ R_1}{R + R_1}
⅓ (R₁ + R) = R₁
R = 3R₁ -R₁ = 2 R₁
R = 2 500
R = 1000 ohm
Compare and contrast fluorescent and incandescent light bulbs.
Answer:
The biggest difference between the two is in how they produce light. Incandescent bulbs produce light by a heating a metallic filament until it starts to radiate light. On the other hand, fluorescent lamps produce light by exciting a gas and causing it to glow.
