Answer:
It is due to the large impulse is imparted on the flour.
Explanation:
A ball is moving faster.
When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.
Impulse = change in momentum
So, as the flour experiences large impulse and large momentum so that the flour spreads out.
If the change in momentum is large so the flour spreads out is more.
Answer:
The distance between the two spheres is 914.41 X 10³ m
Explanation:
Given;
4 X 10¹³ electrons, and its equivalent in coulomb's is calculated as follows;
1 e = 1.602 X 10⁻¹⁹ C
4 X 10¹³ e = 4 X 10¹³ X 1.602 X 10⁻¹⁹ C = 6.408 X 10⁻⁶ C
V = Ed
where;
V is the electrical potential energy between two spheres, J
E is the electric field potential between the two spheres N/C
d is the distance between two charged bodies, m
where;
K is coulomb's constant = 8.99 X 10⁹ Nm²/C²
d = (8.99 X 10⁹ X 6.408 X 10⁻⁶)/0.063
d = 914.41 X 10³ m
Therefore, the distance between the two spheres is 914.41 X 10³ m
Answer:2m/s^2
Explanation:
mass=5kg
Force=10N
Acceleration=force ➗ mass
Acceleration=10 ➗ 5
Acceleration=2m/s^2
Answer: The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close because the kinetic energy of the particles of matter increases with the increase in temperature. In cold foods, kinetic energy is less while in hot foods, kinetic energy is more
hope this helps
