a = (V - V₀) / t = (14 - 4) / 10 = 10 / 10 = 1 m/s²
Answer
A reference point is the starting point you choose to describe the location, or position, of an object. The reference point in the first example is your friend. ... The direction is north, and the reference point is your school. A position is an object's distance in a certain direction from a reference point.
Explanation:
Okay, i worked on this last year, a transverse wave is a wave that vibrates in the direction of its propagation, and a compression wave is a wave that travels closer together!
Answer:
F=1487.52 N
μ = 0.12
Explanation:
Given that
m= 1200 kg
r= 25 m
v= 20 km/hr = 20 x 5/18 m/s
v= 5.55 m/s
To maintain the speed 5.55 m/s ,friction force should be equal to the radial force
Friction force = Radial force(F)
By putting the values
F=1487.52 N
So friction force = 1478.52 N
We also know that
Friction force = μ m g
1478.52 N = μ x 1200 x 10 ( take g =10 m/s²)
μ = 0.12
This is minimum coefficient of static friction required to keep the car in this turn.
Answer:
the unit of work is derived unit because joule is defined the work done by the force aftab 1 newton causing the displacement of one metre something newton metre(n-m) is also used to measuring work.
