Answer:
$0.1584
Explanation:
Power = current×voltage
P = IV................. Equation 1
Where P = power, I = current, V = voltage.
V(t) = 12(1+e-t/30)....................... Equation 2
Where t = 30 hours
Substitute into equation 2
V(t) = 12(1+e-30/30)
V(t) = 12(1+e-1)
V(t) = 12(1.1)
V(t) = 13.2 V.
also, I = 2 A.
Substitute into equation 1
P = 2×13.2
P = 26.4 W.
P = 0.0264 kW.
Energy consumed by the battery = 0.0264×30 = 0.792 kWh.
If, 1 kWh = $0.2
Then,0.792 kWh = 0.2×0.792 = $0.1584
Hence the cost to charge the battery = $0.1584
In general, it is felt that ice ages are caused by a chain reaction of positive feedbacks triggered by periodic changes in the Earth's orbit around the Sun. The last ice age ended about 12,000 years ago. The next cooling cycle would be expected to start about 30,000 years or more into the future.
Ok, so it definitly isn't "The sun released a strong burst of water vapor" because the sun doesn't have water. I'm not too sure about this one " Water evaporated and condensed to form oceans" but I would say yes. "Materials collided due to strong gravitational forces." Yes. That's how the earth was made. "The ozone layer formed to protect against harmful UV ray exposure." Yes. It acts as a sort of filter so we all don't disintegrate as soon as we step outside (bit of exaggeration but whatever). "Water vapor increased during formation of the early atmosphere." yes. I do hope this helps

The answer is A: Ice
The prefix cryo refers to cryoprecipitate, which means a frozen blood product prepared from plasma.
Answer:
a = 1.25m/s^2
Explanation:
Force = mass x acceleration
Given mass M = 48kg and
Force F = 60N
60 = 48 x a
Divide both sides by 48
60/48 = 48 x a/48
1.25 = a
a = 1.25m/s^2
