Answer:
When the velocity of an object changes it is said to be accelerating. Acceleration is the rate of change of velocity with time. ... Acceleration occurs anytime an object's speed increases or decreases, or it changes direction.
Answer: The first electromagnet has a more powerful current than
the second
Explanation:
Since the two electromagnets contain the same types of magnets and wires. If the magnet In the first moves much faster than the second. Therefore:
The first electromagnet has a more powerful current than the second
Because the induced EMF is proportional to the induced current.
Where the induced EMF depends on the speed of the magnet according to the formula below
EMF = BVL
So, increase in speed of the magnet will cause more powerful induced current and emf
If u mean pressure, pressure = Force/Area
Correct me if I am wrong :D
Pressure= hqg
H=depth
q=density
g=gravity
h=0.2
q=7
g=10
0.2*7*10= 14pa
FINAL ANSWER = 14pa
Answer:
80m/s
Explanation:
to find it you have to work it out by using the formula distance divided by speed to find time.
