Answer:
Explanation:
mass of displaced oil = 11 x .9
= 9.9 gm
9.9 x 10⁻³ kg
weight of displaced oil = 9.9 x 9.81 x 10⁻³ N
= .097 N .
buoyant force by oil = .097 N
weight of unknown metal = .1 x 9.8
= .98 N .
weight of metal in oil = .98 - .097
= .883 N .
=
Answer:
The horizontal distance traveled by the ball before it hits the ground is 48.85 meters.
Explanation:
It is given that,
Speed of golf ball, v = 25 m/s
Angle above horizontal or angle of projection, θ = 65°
We need to find the distance travelled by the ball before it hots the ground or in other words we need to find the range. It is given by R.
R = 48.85 m
So, the distance travelled by the ball before it hots the ground is 48.85 meters. Hence, this is the required solution.
What happens to water when it becomes ice? Answer: the water level does NOT change even if it does melt, deposition is the term used when water liquid becomes solid ice, and also the water molecules DECREASE/LOWER speed and join in straight positions.
2) Answer: Conductors of both electrical and heat.
Answer:
Below:
Explanation:
It's the definition of "Cognitive Dissonance".
Answer: A Answers. Assuming that the terminal velocity doesn't change during the fall, then the kinetic energy would remain constant. However the terminal velocity decreases during the fall since the air becomes denser at lower altitudes.
Explanation:
What happens to the KE of an object when it slows down and heats up? - Quora. The kinetic energy goes down and the loss of the kinetic energy is through the production of heat energy. In real world this is due to friction, or an opposing force that decelerates the object, or a combination of both.
