Answer:
The speed of the resistive force is 42.426 m/s
Explanation:
Given;
mass of skydiver, m = 75 kg
terminal velocity, 
The resistive force on the skydiver is known as drag force.
Drag force is directly proportional to square of terminal velocity.
Where;
k is a constant
When the new drag force is half of the original drag force;
Therefore, the speed of the resistive force is 42.426 m/s
Answer: Visible light makes up 35% of natural light.
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
Therefore, <span> it will increase by a factor of 8. Hope this answers the question.</span>
Answer:
2.177088 * 10^-8 N
Explanation:
solution;
mass(m1) = 1 * 10 kg
mass(m2) = 8 * 102 kg
distance(d) = 5m
universal gravitational constant (G) =6.67 * 10^-11
we know that,
gravitational force = (G*m1*m2)/d^2
=((6.67 *10^-11) *(1 *10)*(8 *102))/5^2
=(5.44272 * 10^-7)/25
=2.177088 *10^-8
Gravitational force = 2.177088 * 10^-8
