It’s d energy because it’s referring to power changing because the power unit is (J/s) joule per second known as watt which is the same as implieing power
To determine the force per meter of a light bolt at the equator that carries 20 000 A and is perpendicular to the Earth's magnetic field with a magnitude of 3x10-5 T, we do this:
20000 / 3x10-5 = 666.67x10^6 N/m
The direction of the force would be to the left parallel to the equator.
Answer:
76.9 m/s
Explanation:
total distance travelled is 750m + 250m = 1000m
the total time taken is 13 seconds.
1000m/13s = 76.9 m/s (1dp)
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.
