Answer:
It will increase by a factor of 8.
Explanation:
By Ohm's Law, we can relate current, voltage and resistance. It is expressed as V=IR. That is, there is a direct relationship between voltage and resistance and voltage and current.
V = IR
V1/2V1 = I1R1 / I2R1/4
1/2 = 4I1/I2
I2 = 8I1
0, Because if they are pulling with equal force then they cancel each other out<span />
Answer:
0.349W/m²
Explanation:
We can use the intensity formula [ I = P/T ].
= P / 4πr²
= 60/4π(3.7)²
= 60/4(3.14)(13.69)
= 60/4(42.9866)
= 60/171.9464
≈ 0.349W/m²
Best of Luck!
Answer:
The ball to hit the ground in 0.53 s.
Explanation:
Given that,
Height = 1.4 m
Time t = 0.53 s
Initial speed = 35 m/s
We need to calculate the time when the ball to hit the ground
Using equation of motion

Where, s= vertical height
u= vertical velocity
t = time
h = height
Put the value in equation




Hence, The ball to hit the ground in 0.53 s.
