i believe the equation would be E=mc2
Answer:
sphere moves with a constant terminal velocity.
Explanation:
mass of sphere, m = 0.5 kg
velocity downward, v = 8 m/s
buoyant force = 4 N
fluid friction force = 4 N
Weight of the sphere is acting downward.
W = mg = 0.5 x 10 = 5 N
When the object is immersed in a fluid and it moves in the fluid with constant velocity, it means the net force acting on the object is zero, and the object attains a terminal velocity.
The complete question is this: This figure (Figure 1) shows a container that is sealed at the top by a movable piston. Inside the container is an ideal gas at 1.00 atm, 20.0 ∘C, and 1.00 L. This information will apply to the first three parts of this problem.
A) What will the pressure inside the container become if the piston is moved to the 1.20 L mark while the temperature of the gas is kept constant?
Explanation:
It is given that,
= 1 atm, = 1 L
= ? , = 1.20 L
As the temperature is constant. Hence, find the value of as follows.
=
=
= 0.833 atm
Thus, we can conclude that the pressure inside the container is 0.833 atm.
I believe it would be 127.8 pounds. weight = mass x gravity
<u>Answer:</u>
The correct answer option is C. Kinetic energy from vibration.
<u>Explanation:</u>
The energy of the random motion of the particles of an object is referred to as the internal energy of that object (substance). So the type of energy that makes up most of the internal energy of a solid substance is kinetic energy from vibration.
Internal energy is related to the temperature. When heat is supplied to an object, the molecules vibrate and energy of these molecules increases.
