Answer: The answer is D.
Explanation: Momentum can be defined as mass in motion. All objects have mass so if an object is moving, then it has momentum it has its mass in motion. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
Answer:
I guess the answer is
-The mass and volume of an object determine if it will sink or float
Explanation:
An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
density=mass/volume
Wave speed= Frequency x Wavelength
-> Wavelength= Wave speed divide Frequency
-> 50m/s divide 100Hz= 0.5m
Answer:
The final velocity 
Explanation:
Given data
Mass of merry go round 
= 120 kg
Radius = 1.8 m
Initial angular velocity 
= 0.6 
Mass of boy 
= 25 kg
We know that the final velocity is given by
Put all the values in above formula we get
This is the final velocity.
<span>So the question is to unscramble all of the words that are types of heat-creating energy and they are: LACECHMI, CEIECTLR, IRITONFC, AREOGLHMET, LCRNEAU, ROASL. So LACHECHMI is CHEMICAL, CEIECTLR is ELECTRIC, AREOGLHMET is GEOTHERMAL, LCRNEAU is NUCLEAR and ROASL is SOLAR. </span>
