Answer:
The potential between the plates will decrease.
Explanation:
An insulator is usually placed between the parallel plates and is also called a dielectric because it makes the amount of charge a capacitor can accommodate to increase at a particular potential difference.
Furthermore, the dielectric effect will make the electric field of the charged capacitor which is not connected to a source of supply to decrease.
Now, when the battery is removed, the charge Q remains constant and Capacity C will increase.
Formula for the potential difference is here;
V = Q/C
Since the numerator Q is constant and the denominator C increases, it means the potential difference V will decrease
Answer:
<em>The range is 35.35 m</em>
Explanation:
<u>Projectile Motion</u>
It's the type of motion that experiences an object projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the initial speed of the object, θ the initial launch angle, and the acceleration of gravity, then the maximum horizontal distance traveled by the object (also called Range) is:
The projectile was launched at an angle of θ=30° with an initial speed vo=20 m/s. Calculating the range:
The range is 35.35 m
From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude
VELOCITY AND ACCELERATION
The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.
Given that a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.
Since acceleration =
a = 1000(100 - 0)/6
a = 100000/6
a = 16666.67 m/
And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.
acceleration =
a = 1000(100 - 0)/5
a = 100000/5
a = 20000 m/
From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.
Race car A accelerates at 16666.67 m/, while race car B accelerates at 20000 m/

Answer:
Explanation:
1 ) Force F = dp/ dt , p is momentum
= d/dt (mv)
= v dm/dt
Given dm/dt = 0.1 kg per second.
Force = v x 0.1
= .1 x .1
= .01 N
2 ) work done = force x displacement
Displacement in 1 s = 0. 1 m ( v = .1 m /s )
Work done in one second = .1 X .1
= .01 J
3 ) Velocity is constant so change in kinetic energy is due to additional mass .
Mass deposited in one second
= .1 g
Velocity = .1 m/s
Change in kinetic energy = 1/2 x .1 x .1 ²
= 5 x 10⁻⁴J
4 ) No , they are not the same. It is so because force has to do work against the frictional force offered by the surface on which sand is falling . So rise in kinetic energy is small as compared with work done by the force.
