Answer:
0
Explanation:
The object would be neutral. There are equal numbers of protons and electrons, so the positive and negative charges cancel one another.
Changing frequency of sound does not change the speed of the sound.
Explanation:
- Speed of the sound gets altered when the sound travels from one medium to another.
- Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
- Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
It’s d energy because it’s referring to power changing because the power unit is (J/s) joule per second known as watt which is the same as implieing power
Answer: A net force is the overall force on an object when all the individual forces acting on an object are added together. When there is a net force acting on an object, the force is said to be unbalanced. With balanced forces, equal forces are exerted in opposite directions providing a net force of zero
Answer:
1088.9N/m2
Explanation:
Calculation for What pressure is exerted
First step is to find the area of bottom of the tank using formula
Area=Width*breadth
Let plug in the formula
Area=0.5*0.9
Area=0.45m2
Now let calculate what pressure is exerted using this formula
Pressure=Force/Area
Where,
Force=Mass *Gasoline
Area=Width of the tank* Length of the tank
Let plug in the formula
Pressure=50*9.8/0.5*0.9
Pressure=490/0.45
Pressure=1088.9N/m2
Therefore What pressure is exerted is 1088.9N/m2
