Answer:
Hey Again!
Your answer is 2450 cm3
!
Explanation:
Volume of cylinder = V=πr2h
2.45L = 2450mL
1mL = 1 cm cubed
2450mL = 2450 cm cubed
*substitute values in*
I HOPE THIS HELPS YOU!!
Given : A car starts from rest and accelerates at a constant rate. After the car has gone 50 m it has a speed of 21m/s. What is the acceleration of the car?
Solution : As per the question, initial velocity is 0 m/s and final velocity is 21 m/s. Distance travelled is 50 m and we need to get the acceleration of the car.
We need to use the third equation of motion. Second equation is invalid as time is given in the formula but as per the data third equation is more comfortable.
★ 3ʳᵈ eq. of motion : v² - u² = 2aS ★
Putting all the given values according to the formula we get
<u>Henceforth, acceleration is 4.41 m/s²</u>
pshyical change is a usually reversible change of a substance, as size or shape: Freezing a liquid is a physical change. Compare chemical change.
internal change is when the movement of the particles increases
specific latent heat is the amount of energy per kg (unit mass) required to change ice to water without change in temperature.

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. Furthermore, the angle of reflection<span> is equal to the </span>angle of incidence.<span> Both </span>angles<span> are measured with respect to the normal to the mirror.</span>
