a. Newtonj 3d Low You feel a force against the sole of your foot as you
take a step forward.
b.
A meteor moving in a straight path changes direction
when it flies by Earth.
C.
A full grocery cart that is pushed starts moving and
increases speed, but the same push increases its speed even more when the
cart is empty.
d.
A skateboard moves faster in the same direction it is
pushed.

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

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

Answer:

the answer is D

as an electron is composed of positive charges

Answer:

D.+1°e symbol represents a type of radiation that has the same mass as an electron and a positive charge.

Explanation:

it is 100% correct!

Answer:

Protons and Electrons

For every proton in an atomic center, somewhere, in an orbital, there will be an electron. A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges.

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.

Answer:

Current = 2 Amperes

Explanation:

Given the following data;

Resistance = 8 Ohms

Power = 32 W

To find the amount of current going through the speaker;

Mathematically, power can be calculated using the formula;

Power = current² * resistance

Substituting into the formula, we have;

32 = current² * 8

Current² = 32/8

Current² = 4

Taking the square root of both sides, we have;

Current = √4

Current = 2 Amperes

opaque glass does not allow light to pass through it.

Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion. Think about Jerod again. He applies force with his foot to the ground, whereas the ground applies force to Jerod and the skateboard, causing them to move forward.

Answer:

960 W

Explanation:

F = 800 N

x = 18 m

t = 15 s

Work = Fx= (800 N)(18 m) = 14,400 J

Power = Work / time = (14,400 J) / (15 s) = 960 W

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

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

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.

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.

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

Answer:

The change in temperature is bigger for the first pan which contains 10 mL of water.  

Explanation:

in one pan

mass, m = 10 mL = 10 g

in another pan

mass, m' = 500 mL = 500 g

Heat, H = 3000 J

Specific heat of water, c = 4.2 J/gC

Let the change in temperature in first pan is T and in the second pan is T'.

Use the formula of heat

H = m  c T

For the first pan

3000 = 10 x 4.2 x T

T = 71.42 C

For the second pan

3000 = 500 x 4.2 x T'

T' = 1.42 C

So, the change in temperature is bigger for the first pan.

Answer: The correct option is (B) 0.875 Ω.

Explanation:

Equivalent resistance: It is defined as the sum of the all resistance present in the circuit.

There are two conditions:

(1) Resistors in series

Equivalent resistance, [tex]R_s=R_1+R_2+R_3+R_4........R_n[/tex]

(2) Resistors in parallel

Equivalent resistance, [tex]R_p=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+\frac{1}{R_4}........\frac{1}{R_n}[/tex]

According to the given circuit, the resistors are in parallel arrangement.

Given:

[tex]R_A=2.00\Omega\\\\R_B=4.00\Omega\\\\R_C=8.00\Omega[/tex]

Thus,

Equivalent resistance will be:

[tex]R_p=\frac{1}{R_A}+\frac{1}{R_B}+\frac{1}{R_C}\\\\R_p=\frac{1}{2.00}+\frac{1}{4.00}+\frac{1}{8.00}\\\\R_p=0.875\Omega[/tex]

Therefore, the equivalent resistance of the circuit is 0.875 Ω.
