A
An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.
Explanation:
I think is c not sure though
Answer:
Explanation:
Given
Force required to accelerate the object at the rate of
The weight of the object is
Mass of the object can be identified by dividing the weight by acceleration due to gravity
Answer:
Angle will be
Explanation:
We have given frequency of the sound f = 600 Hz
Vertical opening is of 0.8 meter
So width D = 0.8 m
Velocity of sound v = 340 m/sec
We know that wavelength
Now for the first minimum
The law of Bio Savart is used to show the magnetic intensity because of the availability of magnetic current.
<u>Explanation:</u>
In physics, explicitly electromagnetism, the Biot–Savart law is a condition portraying the attractive field produced by a consistent electric flow. It relates the attractive field to the extent, heading, length, and closeness of the electric flow.
The Biot Savart Law expresses that it is a scientific articulation which shows the attractive field delivered by a steady electric flow in the specific electromagnetism of material science. It tells the attractive field toward the greatness, length, heading, just as closeness of the electric flow.
