Answer:
Keep on moving
Explanation:
Newton's first law 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."
Solids-are molecules that are together at all times( unless changed by a liquid or gas)
liquid-are molecules that move around freely in 1 space but can be changed to solid or gas
gas- molecules that move around freely and can be hot or cold depending
plasma- a material that goes to forming a cell or a liquid without any structual particles
There you go!
Answer:
23 m/s
Explanation:
First, find the time it takes for the car to fall 40 meters.
y = y₀ + v₀ t + ½ at²
0 = 40 + (0) t + ½ (-9.8) t²
0 = 40 − 4.9 t²
t = 2.89 s
Next, find the velocity needed to travel 65 meters in that time.
x = x₀ + v₀ t + ½ at²
65 = 0 + v₀ (2.89) + ½ (0) (2.89)²
v₀ = 22.75 m/s
Rounding to two significant figures, the car's initial speed was 23 m/s.
Its fake some of its real like the space part and the traveling through space part but not the multi dimensional stuff
Answer:
7.2 x 10⁻⁶N
Explanation:
Given parameters:
Mass of Venus = 4.87 x 10²⁴kg
Radius = 6.05 x 10⁶km = 6.05 x 10⁹m
Mass of person = 81kg
Unknown:
Gravitational force = ?
Solution:
To solve this problem, we use the Newtons law of universal gravitation:
Fg =
G is the universal gravitation constant = 6.67 x 10⁻¹¹
Fg =
Fg = 7.2 x 10⁻⁶N
