Answer:
F_net = B -W
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
Explanation:
A hot air balloon is subjected to the force of its weight directed towards the center of the Earth. The thrust due to the cold air released, this thrust is directed upwards.
If we assume that the balloon rises at a constant speed
F_net = B -W
F_neta = ρ g V_body - ρ_body g V_body
The forces of action and reaction are the weight of the balloon that is the force of attraction of the Earth and the outside so the balloon pulls the earth that has an upward direction and is applied to the planet
Ball leaves the table of height 0.60 m
Initial speed of the ball is in horizontal direction which is 2.4 m/s
Now here we can say that time taken by the ball to hit the ground will be given by kinematics equation in vertical direction
here in y direction we can say
due to gravity
now from above equation we have
Now in the same time the distance that ball move in horizontal direction is given as
given that
So it will move a total distance of 0.84 m where it will land
V = I · R = (3.8 Amperes) · (32 ohms) = 121.6 volts
Answer:
They are both proportional to the product of their masses and inversely proportional to the square distance between the masses.
Answer:
6-16km
