What are two conductive materials separated by an insulator,and used to store electric potential energy?

A race cars velocity increases from 6.0 m/s to 36 m/s over a 5.0 s time interval. What is It’s average acceleration?

Sonja [21]

The acceleration of the race car is 6 m/s²

The given parameters;

initial velocity of the race car, u = 6 m/s

final velocity of the race car, v = 36 m/s

time of motion, t = 5 s

Acceleration is defined as the change in velocity per change in time of motion.

The acceleration of the race car is calculated as follows;

$a=\frac{v-u}{t} \\\\a = \frac{36-6}{5} \\\\a = 6 \ m/s^2$

Thus, the acceleration of the race car is 6 m/s²

Answer:

The density of a material affects the speed that a wave will be transmitted through it. In general, the denser the transparent material, the more slowly light travels through it.

A proton and a deuteron are moving with equal velocities perpendicular to a uniform magnetic field. A deuteron has the same char

Leokris [45]

Answer:

option (b)

Explanation:

mass of proton, mp = m

mass of deuteron, md = 2m

charge on proton, qp = q

charge on deuteron, qd = q

The magnetic force on the charged particle when it is moving is given by

F = q v B Sinθ

where, θ is the angle between the velocity and magnetic field.

Here, θ = 90°

Let v is the velocity of both the particle when they enters in the magnetic field.

The force on proton is given by

Fp = q x v x B ...... (1)

The force on deuteron is

Fd = q x v x B .... (2)

Divide equation (1) by equation (2)

Fp / Fd = 1

Thus, the ratio of force on proton to the force on deuteron is 1 : 1.

Thus, option (b) is correct.

The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws. A crab with a body weigh

frez [133]

Answer:

The weight of body is 1.3040 gram.

Explanation:

Given that,

The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws.

Suppose a crab with a body weight of 1.8 gram has claws weighing 1.1 gram.

Estimate the weight of a fiddler crab with claws weighing 0.85 gram.

Determine the weight of crab body

We need to calculate the value of proportional constant

$y\propto x^{1.25}$

$y=kx^{1.25}$

$k=\dfrac{y}{x^{1.25}}$

Put the value into the formula

$k=\dfrac{1.8}{1.1^{1.25}}$

$k=1.5978$

We need to calculate the crab weight

$y=kx^{1.25}$

Here, x = 0.85 g

Put the value into the formula

$y=1.5978\times(0.85)^{1.25}$

$y=1.3040\ gram$

Hence, The weight of body is 1.3040 gram.
