Centripetal acceleration is given by the formula

Since we know the value of the acceleration is 9.8 m/s² and we know r, we can solve for the speed, which is the magnitude of v. Note the value of a is just the acceleration due to gravity, which is what makes the rocket orbit and not fly off into space.
Plasma is like a gas that has no fixed volume, but gases are electrically neutral but Plasma is an ionized gas in which the electrons are ripped apart from the atom. It also conducts electricity
The gas in tube light is a plasma gas

Answer:
The right solution is "50200 days".
Explanation:
Given:
Calories intake,
= 6000 kcal,
or,
= 
Force,
= 500 N
As we know,
⇒ 
Or,
⇒ 
By putting the values, we get



hence,
The number of days will be:
= 
= 
Answer:
The distance is 20 m.
Explanation:
Given that,
Mass of two blocks = 4.0 kg
Initial velocity = 35 m/s
Angle = 45°
Time = 2 sec
After, they become untied, center of mass trajectory will not change:
We need to calculate the distance
Using equation of motion

Where, u = initial velocity
g = acceleration due to gravity
t = time



Hence, The distance is 20 m.
