Answer:
Explanation:
The work done by the gravitational force is given by:
(1)
Where:
is the variation in potential energy
is the Gravitational constant
is the mass of the Earth
is the mass of the spacecraft
is the distance from the center of the Earth to its surface
is the distance between the Earth and Pluto
Rearranging (1):
(2)
(3)
Finally:
To solve this problem we will apply the concepts related to resistance as a function of temperature, product of the relationship between the squared voltage and the power. Mathematically this is,
Here,
R = Resistance (At function of temperature)
v = Voltage
P = Power
Then we have,
R at 140°C (7 times room temperature),
The relationship between normal temperature and increased temperature would then be given by,
Therefore the correct value of the group of answer is 1350
Answer:
easy
speed = distance/time = 50 / 0.3 = 500/3 m/sec
Answer:
False
Explanation:
Because if you were running on a tredmill they have clips that target your heart rate so it does not go to far up or to low.
When a ball is dropped from building, it will experience two forces: gravitational force( acting in downward direction) and air resistance(acting in upward direction i.e opposite to the motion of ball). This air resistance can be neglected because coefficient of viscosity of air is very less. So only gravitational force is responsible for downward motion of the ball.
