Answer:
18750 kg-m/s
Explanation:
Momentum = mass x velocity
Initially, the velocity vector is . At the same height, the x-value of the vector will be the same, and the y-value will be opposite (assuming no air resistance). Assuming perfect reflection off the ground, the velocity vector is the same. After 0.2 seconds at 9.8 seconds, the y-value has decreased by , so the velocity is .
Converting back to direction and magnitude, we get
Balanced. They’re equally as strong so as their arm wrestling, neither of the men’s hands go down. Because they’re equally/balanced as strong.
Answer:
Explanation:
Same numbers of protons but different number of neutron so i would go for A same atomic number different number of neutrons
Answer:
Q = 116.8 J
Explanation:
Here given that the temperature of 1 L hydrogen is increased by 90 degree C at constant pressure condition.
So here we will have
here we know that
n = number of moles
for ideal diatomic gas molar specific heat capacity at constant pressure is given as
now we have
