Answer 1
Answer: 1 . W=mass times acceleration due to gravity
60kg times 9.8m/s2
= 588N

2. W=mg
1176N=m times 9.8
m=120kg


3. 1 hour=3600s
24 hours=?
24 times 3600
= 86400 seconds


4. 1000g=1kg
25000g=?
25000 times 1 divide by 1000
=25kg



5. 1000000mg=1kg
123000000=?
123000000 times 1 divide by 1000000
=123 kg

how far can a person run in 15 minutes if he or she runs a at an average speed of 16 km/hr? what is the runners distance traveled in miles

Answers

To find this, we would divide 60 by 15 because there is 60 minutes in an hour and we're trying to find how much of 16 km he can run in 15 minutes. When we divide 60 by 15 we get 4. Now we divide 16 by 4 to get 4. So he can run 4 km in 15 minutes.

The light in this diagram is producing light.Which best describes the process of energy conversion to accomplish this?



A.
Electrical energy turns the rod. This energizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.

B.
Mechanical energy turns the rod. This electrifies the coil. The electrified coil generates a magnetic field. The magnetic field goes through the wires as electricity to power the lightbulb.

C.
Mechanical energy turns the rod. This magnetizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.

D.
The magnetic energy in the coil turns the rod. The rod generates an electric current. The electric current goes through the wires to power the lightbulb.

Answers

It could be D or B. I'ts a hard question, but I'm going with B. Hope I got you the right answer. :)
I think the one that describes the process of energy is B. It shows step through step and at the end it tells you how. I hope this helped.

Answers

A chlorine ion contains 17 protons and 18 electrons, which gives it a net charge of -1 1234. Therefore, the correct answer is A. -e.

Tamika inflates and ties off a balloon in her classroom and then takes it outside on a cold, winter day. Immediately, she notices that the balloon has gotten a little bit smaller. Why does this occur?A) because there are fewer molecules in the balloon outside
B) because the air pressure is significantly higher when it is colder
C) because the molecules in the balloon have slowed down with the temperature
D) because the molecules shrink in size when exposed to the colder, outside air

Answers

The balloon has gotten a little bit smaller C) because the molecules in the balloon have slowed down with the temperature.

Answer: Option (C) is the correct answer.

Explanation:

When the balloon was placed inside Tamika's classroom then the temperature was high as compared to the temperature outside the classroom.

As a result, gas molecules were in rapid motion but when balloon was placed outside the classroom then due to cold, there was decrease in temperature.

Therefore, the movement of gas molecules will slow down and the molecules will come slightly close to each other.

Hence, there will be shrinkage in the size of balloon.

Thus, we can conclude that the balloon has gotten a little bit smaller because the molecules in the balloon have slowed down with the temperature.
