Answer:
The free fall acceleration on the surface of this planet is 4.35 m/s²
Explanation:
Given that,
Mass of planet
Radius of planet
We need to calculate the free fall acceleration on the surface of this planet
Using formula of gravity
Where, = mass of planet
= radius of plane
Put the value into the formula
Hence, The free fall acceleration on the surface of this planet is 4.35 m/s²
Answer:
Final velocity of ball = 20 m/s
Explanation:
Given:
Height when ball released = 20meter
Find;
Time taken to fall
Final velocity of ball
Computation:
Initial velocity of ball = 0 m/s
Acceleration due to gravity = 10 m/s²
Using equation of motion;
S = ut + (1/2)(g)(t²)
20 = (0)(t) + (1/2)(10)(t²)
20 = 5(t²)
(t²) = 20 / 5
(t²) = 4
Time taken to fall = 2 second
V = u + at
V = 0 + (10)(2)
Final velocity of ball = 20 m/s
Answer: equal to one
Explanation:
Because is the sum of the relative frequencies.
Answer: The correct answer is "magnetic field".
Explanation:
A magnetic field is produced around the current carrying wire.
If you bring compass needle around the current carrying wire then it shows the deflection which indicates that there is a magnetic field around the current carrying wire.
Magnetic fields are the area around the surrounding of magnet in which magnetic force can be experienced.
Therefore, a magnetic field is produced around a wire when an electrical current is in the wire.
If you change the mass, you change anything that depends on mass. But I suspect the word you're looking for is "momentum"
