Large surface area, as more particles are able to bump into one another and transfer heat.

The same net force is applied to two bodies. The first body acquires half of the acceleration of the second body. What is the re
Yanka [14]

The mass of the first body is double the mass of the second body.

This all revolves around Newtons 2nd law of motion that states F=m*a.

If we understand that body one has the same force applied but half of the acceleration than body two, we can easily understand that it has to do something with the objects mass. This is because mass and acceleration in newtons 2nd law are inversely proportional. This means if and objects force stays the same, but it’s mass doubles, then the acceleration must be half its original value. And if the acceleration doubles and the force stays constant than the mass must have halved from its original value. It sounds quite complicated but it’s very simple. Hopefully this helps!!!

Electricity may be categorized as static or current. how are these two types of energy different
arlik [135]
Hello!

Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.

Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)

AveGali [126]
1) The type of heat transfer is radiation (ie the sun's rays)
2) Not entirely sure what you mean but it is possible with this equation: KE = 3/2kT with k being the Boltzmann's Constant and T the temperature in Kelvins
3) True? Not really a question.
4) This would be emissivity
5) Thermal Energy
6) Celsius
7) A thermometer

A rocket blasts off. In 10.0 seconds it is at 10,000 ft, traveling at 3600 mph. Assuming the direction is up, calculate the acce
Andrei [34K]

Answer:

Explanation:

Givens

t = 10 seconds

vi = 0

vf = 3600 mph

a = ?

d = 10000 feet

Formula

a = (vf - vi)/t

Solution

vf = 3600 mph * 1 hr / 3600 seconds * 5280 feet / 1 mile = 5280 ft / sec

a = (5280 - 0)/10

a = 528 ft/sec^2
