Answer:
The total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Not at all. Density on its own is not sufficient
Explanation:
Sky appears blue because of Scattering.Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Explanation:
We have,
Radius of pizza, r = 18 m
Potential difference, V = 575 V
Stored electrical potential energy, E = 3.31 J
The area if an air-filled capacitor with parallel plates is equal to that of the pizza. It means,
The stored potential energy in a capacitor is given by :
C is capacitance
The formula of the capacitance of a parallel plate capacitor is given by :
d is plate separation of this capacitor
Given:
Force, F = 30 N
Acceleration, a = 2 m/s^2
Let's determine the mass of the object.
To find the mass(m) of the object, apply the formula below:
Rewrite the formula for mass(m):
Where:
F = 30 N
a = 2 m/s^2
Thus, we have:
Therefore, the mass of the object is 15 kg
ANSWER:
15 kg
