Answer:
0.51
Explanation:
m = Mass = 70 kg
g = Acceleration due to gravity = 9.81 m/s²
t = Time taken
u = Initial velocity = 80 km/h = 80/3.6 = 22.22 m/s
v = Final velocity
a = Acceleration
s = Displacement = 50 m
Kinetic coefficient of friction between the road and the crate is 0.51
The force produced on a particle of charge q by an electric field of intensity E is
in our problem, the force is F=5.0 N while the charge is q=2.0 C, so we can find the intensity of the electric field:
The relationship between electric field intensity and potential difference
between two points A and B is
where d is the distance between the two points. By using d=6.0 m, we find
where the negative sign means that the initial point, VA, is at higher potential than the final point VB.
Answer:
If a ray of light hits the surface of a sheet of glass, some light will be reflected by the surface of the glass. However, much of the light will pass through the glass, because glass is transparent. ... This 'bending of a ray of light' when it passes from one substance into another substance is called refraction.

false here is why :)
Explanation:
Regular, moderate-intensity physical activity reduces the risk of developing coronary heart disease and can reduce the likelihood of dying from heart disease.
hope this helped.
Answer:
d. There is no way of knowing the phase composition without more information.
Explanation:
There is no way to ascertain the phases present in the container when equilibrium is established because we are not furnished with enough information.
- The most important information needed to have a deeper understanding and provide solution is temperature.
- Liquid water and ice can both exist at the same temperature.
- So we cannot conclude based on the information at hand.
