A vector has an x-component
of 19.5 m and a y-component
of 28.4 m.
Find the magnitude of the
vector.
Answer:
34.45m
Explanation:
Magnitude of a vector is equal to the square root of sum of squares of x & y vectors.
Magnitude = [tex]\sqrt({x^2} + {y^2})[/tex]
= [tex]\sqrt({19.5^2} + {28.4^2})[/tex]

Discuss advantages and disadvantages of tissue culture.
Answer:
Explanation:
ADVANTAGES OF TISSUE CULTURE
There are several advantages to using the tissue culture process. We already mentioned its effectiveness in helping developing countries to increase food production, but what are some other advantages that may be relevant to you?
The new plantlets can be grown in a short amount of time.
Only a small amount of initial plant tissue is required.
The new plantlets and plants are more likely to be free of viruses and diseases.
The process is not dependant on the seasons and can be done throughout the year.
You need only a relatively small space to perform the process (ten times the plants in one-tenth of the space).
On a larger scale, the tissue culture process helps to supply the consumer market with new subspecies and variety.
People looking to cultivate challenging plants such as specific breeds of orchid find more success with the tissue culture process than traditional soil.
DISADVANTAGES OF TISSUE CULTURE
Tissue Culture can require more labor and cost more money.
There is a chance that the propagated plants will be less resilient to diseases due to the type of environment they are grown in.
It is imperative that, before being cultured, the material is screened; failure to pick up any abnormalities could lead to the new plants being infected.
While the success rate is high if the correct procedures are followed, success with the tissue culture is not a guarantee. There is still a chance that the process triggers a secondary metabolic chemical reaction, and the new explants or cells' growth gets stunted, or even die off.

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.

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.

(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.
