Physics
1 answer:
Tasya [4]3 years ago
3 0

Answer:

N = 3600 N

Explanation:

centripetal acceleration requirement is

ac = v²/r = 20²/50 = 8 m/s²

As the only available acceleration is gravity, centripetal acceleration must come from that,

This makes the "weight" that the road senses and must counteract

N = m(g - ac)

N = 2000(9.8 - 8)

N = 3600 N

Which physical phenomena is responsible for the earth’s sky appearing blue? scattering reflection dispersion refraction
klio [65]

Answer:  Scattering reflection

Alinara [238K]

if i am changing velocity, i must also have <u>acceleration</u> and a net <u>force</u>

<h2><u>Newton's</u><u> </u><u>first</u><u> </u><u>law</u><u> </u><u>of</u><u> </u><u>motio</u><u>n</u></h2>

  • Newton's first law of motion states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

According to Newton's first law of motion, without a force acting on an object, its velocity does not change. The net force acts on an object to change its velocity and cause acceleration.

Barnard’s Star is a red dwarf. It is located 5.9 light years from Earth. (One light year is the same as 9.46 trillion kilometers
mote1985 [20]
A star is located 5.9 light years from Earth.
We know that : 1 light year = 9.46  trillion kilometers.
We will calculate the distance in trillion kilometers multiplying the number of light years by 9.46:
5.9 * 9.46 = 55.814
Answer: The distance is 55.814 trillion km.
