Subtracting a negative number follows the same process as a positive number

Physics
1 answer:
Sav [38]3 years ago
6 0
This would be true!

When you subtract a positive number, it goes to the left of the number line. When you subtract a negative number, it goes to the left of the number line.

The thing that confuses most people is that the first number (when negative) continues to increase as a negative. It follows the same process, just different signs.

I hope this helps!

A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point
Nonamiya [84]

Answer:

1.52 m

Explanation:

We are given that

Maximum force=F=679 N

Mass of rock ,m=385 kg

Distance,d=0.233 m

We have to find the  minimum total length L of the rod required to move the rock.

Torque on rock=T_1=mgd=385\times 9.8\times 0.233=879.11 N

Where g=9.8m/s^2

Torque on man=T_2=Force\times distance=(L-d)\times 679=(L-0.233)\times 679

T_1=T_2

(L-0.233)\times 679=879.11

L-0.233=\frac{879.11}{679}=1.29

L=1.29+0.233=1.523\approx 1.52 m

Hence, the minimum total  length of rod=1.52 m

When you use paper money to pay for food, the money is a _____.
Tpy6a [65]

Answer: The correct answer for the fill in the blank is - medium of exchange.

Explanation-

When we use paper money to pay for food, the money is a medium of exchange as  we are exchanging our money with their food. So, it plays a role of medium of exchange in purchasing our food.

On the other hand, unit of account is also a feature of money but it only indicates the price of food at which we are purchasing it. Store of value is used when we store our money as a wealth, then it becomes store of value .

Hence, medium of exchange is the correct answer.

What is the best prediction for what will happen when all of the hydrogen in the sun has undergone fusion? helium nuclei will sp
Lena [83]

Helium nuclei splitting to form hydrogen, and the Sun will no longer release energy will occur when all the hydrogen in the sun undergoes fusion.

<h3>What is Fusion?</h3>

This occurs when two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.

In a situation where all the hydrogen in the sun has undergone fusion, the helium nuclei will split to form hydrogen, and the Sun will no longer release energy.
