Answer:
If both the maximum voltage and current are exceeded in a resistor, that the point will lie in the thermal breakdown of the resistor.
Explanation:
This indicated that there will be an abundance of free electrons which will be available freely. This abundance of the electrons in a conductor, will result in the reduction of the overall conductivity. whereas in an insulator or semiconductor this will enhance the overall conductivity.
As the point lies in the thermal breakdown, the Ohm's law is no longer valid and thus no analytical solution can be presented in this regard.
Answer:
7 mm per year
Explanation:
It is given that :
The Pacific plate is moving towards north at = 29 mm per year
The Pacific plate is moving towards west at = 20 mm per year
We have to calculate the total relative motion towards the northwest.
So we have to find the resultant of the two motions.
Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.
Therefore, finding their resultant,


R = 7
Therefore, total relative motion towards the northwest is 7 mm per year.
Answer:
D. Is Zero
Explanation:
The acceleration on projectiles travelling through the air is only caused by gravity. This equal 9.81 m/s^2.
Other than gravity, there is no source of acceleration. Only air resistance causes projectiles of different surface areas to slow down at different rates.
As friction is not considered here (because no statement about surface areas of projectiles is given in the question), we do not need to consider it's effects and thus ONLY GRAVITY MATTERS.
Since gravity acting on both objects is equal, they have no acceleration relative to one another.
The masses are equal.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
I hope that this helps you!
Answer: No
Explanation:
Momentum
refers to how much force is needed to change the motion of a body or object by changing its direction or braking it. In addition, momentum is directly proportional to the mass
and the velocity
:

Now, assuming both the object and the porcelain vase have the same velocity
but different mass, and assuming the mass of the vase is greater than the mass of the object; the momentum of the porcelain vase will be also greater than the momentum of the object.
Hence, the object will not have enough momentum to brake the vase.
