A 5 kg skateboard moves at 7 m/s². What is the force of the skateboard?
2 m/s
2
12
7 m/s
35 N

Answers

Answer 1
Answer: The answer is 35 N.

Force is mass times acceleration: F = m * a

The force is unknown: F=? The unit of force is N (N = kg * m/s²).

But, we know:
mass: m = 5 kg
acceleration: a = 7 m/s²

So, the force is:
F = 5 kg * 7 m/s²
F = 35 kg * m/s²
F = 35 N.

Answers

The spinal cord

The spinal cord part of the central nervous system is involved in this automatic response.

The spinal cord is a long, tiny tube of nervous tissue that support cells which passes from the end of the brainstem to the bottom of the spine. The central brain nervous system is made up of the spinal cord and the brain. The spinal cord is the center for coordinating many reflexes and it plays major roles in the transmission of nerve signals (messages) between the brain and the rest of the body.

What usually accompanies a cold spell in Minnesota?O A. The polar jet stream moves south.
O B. The polar jet stream moves north.
O C. The horse latitudes moves north.
O D. The doldrums moves south.

Answers

The polar jet stream moves south is accompanies a cold spell in Minnesota. Therefore, option (A) is correct.

What do you mean by polar jet stream?

Polar jet stream is a belt of strong upper-level breezes that sits on the polar front. The winds generally move in a westerly direction in midlatitudes and are strongest at the tropopause, the upper boundary of the troposphere.

The convergence of cold air masses coming down from the Arctic and warm air coming up from the tropics creates the jet. Profound box and soak edges arise as the denser virus air sinks and redirects warm air locales north, giving the fly stream its wavy appearance.

The northern polar jet stream is the most important jet stream for aviation and weather forecasting on Earth because it is much stronger and lower in altitude than the subtropical jet streams.

Trace the flow of energy through a typical food chain (describing "what eats what"), including the original source of that energy and its ultimate form after use. Underline each form of energy and energy-storing molecule, and boldface each process which transfers or transforms energy.Can someone explain to me what exactly I'm supposed to do for this and give me guidelines.

Answers

You need to draw a food chain starting with something small like bacteria and and getting back around the loop to bacteria again( explaining what the the previous organism does to the next for example it eats it). Then you need to underline the organisms/animals. Then write in bold the way it got the energy from the previous one( for example if it eats it )
