Answer:
8.6 m/s
Explanation:
We can find the final velocity of the dog by using the following SUVAT equation:
where
u is the initial velocity
a is the acceleration
d is the distance covered
For the dog in the problem, we have
u = 1.5 m/s
And the distance covered is
d = 3.0 m
Therefore, we can re-arrange the equation to find the final velocity, v:
Answer:
The correct option is that both the ends will remain neutral.
Explanation:
As the rod is grounded all of the prolonged charge will be converted to ground so the overall charge on the rod in absence of the charged ball will be equal to zero.Such that the both ends will not bear any charge.
The answer is might be 352
Answer:
If there isn't this type of mechanism, the whole setup will blow even if only one lamp burns out. Doing this mechanism is to decrease the overall resistance resulting in an increased current (Since resistance and current are inversely related) which is the best to blast the fuse.
The force exerted by the explosion on the piston is 2.4 N.
The given parameters:
- <em>Pressure of the explosion on piston, P = 300 Pa (N/m²)</em>
- <em>Surface area of the piston, A = 80 cm²</em>
The force exerted on the piston by the explosion is calculated as follows;
F = PA
where;
A is the area of the piston in m²
The surface area of the piston in square meter is calculated as follows;
The force exerted by the explosion on the piston is calculated as follows;
The complete question is here:
In a car engine, fuel is ignited within a cylinder to cause an explosion that moves a piston. If the explosion exerts 300 Pa of pressure on a piston with a surface area of 80 cm^2, what is the force exerted on the piston?
