Answer:
c human have eukaryotic cell
Fusion needs to force molecule together
they also need to move fast enough to colide (tempureature) there is a minimum tempurature of 18,000,000 F or 9999982.2222 celcius or
I would say pressure and tempurature, but I would choose pressure because this extremem pressure could make the requiared tempureature
Answer:
A) The direction of impulse is the opposite direction to the velocity direction of travel of the baseball.
B) Magnitude of Impulse = 0.6175 N.s
Explanation:
A) From the question we see that there is no change in direction and thus the impulse will be in exactly the opposite direction to the velocity direction of travel of the baseball.
B) From momentum and impulse we know that;
Impulse = change in momentum
Thus, impulse = (V2-V1)m
So;
(10.1 - 14.3)m/s x 0.147 kg = -0.6175N.s
(The negative sign indicates an opposite direction to that of the velocity)
Thus, the magnitude of the impulse is 0.6175 N.s

Answer:
a. Power = 1000 Watts or 1 Kilowatts.
b. Current = 4 Amperes.
Explanation:
Given the following data;
Energy consumed = 1.8MJ = 1.8 × 10^6 = 1800000 Joules
Voltage = 250V
Time = 30 minutes to seconds = 30 * 60 = 1800 seconds
To find the power rating;
Power = energy/time
Substituting into the equation, we have;
Power = 1800000/1800
Power = 1000 Watts or 1 Kilowatts.
b. To find the current taken from the supply;
Power = current * voltage
1000 = current * 250
Current = 1000/250
Current = 4 Amperes.
