Answer:
6.00 x 10⁻⁸N
Explanation:
Given parameters:
Mass of each dump trucks = 1500kg
Distance between them = 50m
Unknown:
New gravitational force between them = ?
Solution:
From Newton's law of universal gravitation,
F =
F is the gravitational force
G is the universal gravitation constant
m is the mass
r is the distance
F =
= 6.00 x 10⁻⁸N
Speed uses distance and velocity uses displacement in its calculation.
For 100 m race, distance = displacement. Hence speed = velocity
For 400m race, distance ≠ displacement. distance = 400m whereas displacement = 0m. Hence speed ≠ velocity
Answer:
It is not correct because the amplitude of the waves can be bigger than others and the graph can be going up and down
Explanation: I got the question right
Answer:
It will be A. So since its 2 times more the kinetic energy. But then you have to square it 2^2 = 4
A) Up is the direction of the magnetic field at point Z.
