Answer:

Explanation:

Temperature is directly proportional to thermal energy of a body.

Thermal energy is one of the numerous forms of kinetic energy which dependent on the motions of the particles in a body.

When the temperature of a body increases, it possess more kinetic thermal energy. In this case, the molecules of the body gains more energy and begins to vibrate until they attain maximum kinetic energy.

The higher the temperature the more the kinetic energy.

An especially violent lightning bolt has an average current of 1.89 x 103 A lasting 0.133 s. How much charge is delivered to the

Rasek [7]

<h2> Charge = 25.9 $Ampsec^{-1}$ </h2>

Explanation:

Given,

The average current (I) = ${1.89} \times {103 A}$ and

Time period (T) = 0.133 s

The charge is calculated by multiplying the current to the time period.

Hence,

To find, the charge delivered to the ground by the lightning bolt(Q) = ?

By applying the formula of charge that is-

Charge(Q) = $Current(I) \times Time(T)$

∴ Charge(Q) = ${1.89} \times {103 A}$ $\times 0.133 s$

= 25.89111 $As^{-1}$

= 25.9 $As^{-}$

<h3>Thus, the charge of 25.9 $Ampsec^{-1}$ is delivered to the ground by the lightning bolt.</h3>

Answer:

The expression for the time taken by an object to move with a speed at some distance is,

t=<u> </u><u>d</u><u>/</u><u>v</u>

Suppose a gliding 2-kg cart bumps into, and sticks to, a stationary 5-kg cart. If the speed of the gliding cart before the colli

Thepotemich [5.8K]

Answer:

Therefore,

Final velocity of the coupled carts after the collision is

$v_{f}=4\ m/s$

Explanation:

Given:

Mass of Glidding Cart = m₁ = 2 kg

Mass of Stationary Cart = m₂ = 5 kg

Initial velocity of Glidding Cart = u₁ = 14 m/s

Initial velocity of Stationary Cart = u₂ = 0 m/s

To Find:

Final velocity of the coupled carts after the collision = $v_{f}=?$

Solution:

Law of Conservation of Momentum:

For a collision occurring between two objects in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

It is denoted by "p" and given by

Momentum = p = mass × velocity

Hence by law of Conservation of Momentum we hame

Momentum before collision = Momentum after collision

Here after collision both are stuck together so both will have same final velocity,

$m_{1}\times u_{1}+m_{2}\times u_{2}=(m_{1}+m_{2})\times v_{f}$

Substituting the values we get

$2\times 14 + 5\times 0 =(2+5)\times v_{f}$

$v_{f}=\dfrac{28}{7}=4\ m/s$

Therefore,

Final velocity of the coupled carts after the collision is

$v_{f}=4\ m/s$
