C. Gravity acts on all objects in the universe.
Explanation:
Isaac Newton with his studies understood that the force of gravity acts on all objects with mass in the universe, and it is the same force that causes an apple to fall from a tree and that keeps the Earth in motion around the Sun.
Newtons also created a formula that allows us to calculate the force of gravity between two objects:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects
Answer:
x = 333.33 [m]
Explanation:
To solve this problem we must use the following kinematics equation.
where:
Vf = final velocity = 0
Vi = initial velocity = 20 [m/s]
a = desacceleration = 0.6 [m/s^2]
x = distance [m]
Note: the final speed is zero as the body finishes its movement.
Now replacing:
0 = (20)^2 - (2*0.6*x)
1.2*x = 400
x = 333.33 [m]
I think it is 500 cm. Hope I helped!
Answer:
M = 1073 Mev/c2
u = 0.95 C
Explanation:
given data:
m1 =135 Mev/c2
v1 = 0.53 c
m2 = 938 Mev/c2
v2 = 0.98 c
from conservation of momentum principle we have
...............1
Total mass of INITIAL particle M =m1+m2 = 1073 Mev/c2
using equation 1
solving for u we get
u = 0.95 C
