The temperature is the degree on intensity of heat in a specific place. Usually, the temperature of thermic neutrality is 70 Fahrenheit or 21 Celsius.
Hope this Helps! :)
Photosynthesis is a good one you can really explain with pictures
Answer: 3MW
Explanation:
W = 1/2 mv^2
W = 0.5 x 1200 x 25^2 = 375 kW
T = 8s
P= 335 x 10^3 x 8 = 3,000 kW = 3MW
Good morning.
Yes, it is possible.Energy is a scalar quantity. The value of the potential energy is calculated the following way:
Where
m is mass,
g is the acceleration of gravity and
h is the height.
Note that the height depends on the adopted referential, therefore, if we adopt, for example, a referential on the floor, if we dig a hole that has a depth of 1 meter, a ball that is put inside the hole will have negative potential energy due to the adopted referential, since
h is negativa in this case.
