Answer:
(a) The motion is uniform
(b) 11.11 m/s
Explanation:
(a)
From the table below, the motion of the bus is uniform.
(b)
Speed(s) = Δd/Δt
s = Δd/Δt............. Equation 1
From the table,
Given: Δd = 10 km = 10000 m, Δt = 15 minutes = (15×60) = 900 seconds
Substitute these values into equation 1
s = 10000/900
s = 11.11 m/s
The earth has less creators because there is a protective atmosphere which makes the asteroids burn up before they hit the surface of earth. Which means by the moon not having an atmosphere small rocks are easily colliding with the moons surface.
Answer:
1 N
Explanation:
First the equation is momentum = Force / distance
20 cm = 0.2 m
5 N/m = F / 0.2 m
F = 1 N
I’m sorry i don’t know the answer
15.49 should be the answer if that is 12 watt battery.
