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:
v = 0.33 m/s
Explanation:
The final velocity of the skier and boat can be calculated by conservation of the lineal momentum:

<u>Where:</u>
m1: is the mass of the water skier = 62.0 kg
m2: is the mass of the boat = 775 kg
v1i: is the initial velocity of the water skier = 4.50 m/s
v1f: is the final velocity of the water skier = ?
v2i: is the initial velocity of the boat = 0
v2f: is the final velocity of the boat = ?
Since the final velocity of the skier is the same that the final velocity of the boat, we have:
Therefore, the final velocity of the skier and boat is 0.33 m/s.

Answer:
Researchers have discovered the positive impact of moderately elevates carbon dioxide own to Ocean acidification. Also the growth rate of one reef-building coral actually improved with moderate ocean acidification.
Answer:
The height (h) will be:
Explanation:
The scape speed equation is given by:

Now, the speed of the missile is


Using the conservation of energy, we can find the maximu height of the missile.



Let's recall that g = GM/R², using the equivalence principle. When R is the radius of the earth and M is the mass of the earth.

Therefore the height (h) will be:
