Answer: The acelaration is 2 m/s^2
Explanation: Using the second Newton law
The total force acting over the object is equal to the mass x accelaration, that is:
We considerer the applied force to the object equal to 25N
and the friction force of 15 N
25N-15N= m*a
The tension in the string corresponds to the gravitational attraction between the Sun and any planet.
Answer:
Explanation:
Let the separation required be d .
Force between rod = 10⁻⁷ x 2 I₁ I₂ L / d
where I₁ and I₂ are current in them , d is distance of separation and L is length of wire .
Force between rod = 10⁻⁷ x 2 x 1200 x 1200 x .69 / d
= .1987 /d
Restoring Force by spring = k x where k is force constant and x is compression .
= 130 x .03
= 3.9 N
For balancing
Restoring Force by spring = Force between rod
.1987 /d = 3.9
d = .1987 /3.9
= .0509 m
= 5.09 cm .
Answer:
False
Explanation:
ac = v^2/r
acceleration is not dependent on the mass of the orbiting object.
Because temperature sets a limit to how much water vapor can be in the air.
