No one can answer that kind of question since it was a specific project.

3. Imagine a 10kg block moving with a speed of 20m/s<br> calculate the kinetic energy of this block

MatroZZZ [7]

The formula of the kinetic energy is:
$E_{k} = \frac{m v^{2} }{2}$
where m is a mass of the object, v is speed of the object at the moment of time. So we have:
$E_{k} = \frac{10* 20^{2} }{2} = 2000J$
The answer is 2000 Joules.

A 1.0 kg piece of copper with a specific heat of cCu=390J/(kg⋅K) is placed in 1.0 kg of water with a specific heat of cw=4190J/(

Valentin [98]

Answer:

The temperature change of the copper is greater than the temperature change of the water.

Explanation:

deltaQ = mc(deltaT)

Where,

delta T = change in the temperature

m =mass

c = heat capacity

$\frac{(deltaT)_{Cu}}{(deltaT)_{w}}=\frac{4190J/kg.K}{390J/kg.K}\\ \\(deltaT)_{Cu}=10.74(deltaT)_{w}$

The temperature change in the copper is nearly 11 times the temperature change in the water.

So, the correct option is,

The temperature change of the copper is greater than the temperature change of the water.

Hope this helps!

c. A car was running with a velocity of 20m/s. what will be its velocity after 30s if it's acceleration is 5m/s2

weqwewe [10]

$\large \mathfrak{Solution : }$

let's use first equation of motion to solve this ;

$\boxed{ \boxed{ v = u + at}}$

$v = 20 + (5 \times 30)$

$v = 20 + 150$

$v = 170 \: \: m/s$

Velocity after 30 seconds = 170 m/s
