Becquerel works with uranium and its compounds, they consist of a mixture of alpha, beta, and gamma rays

Becqerel rays are quickly established that a variety of uranium salts, whether phosphorescent or not, have the same property; proving that the radiation is an intrinsic characteristic of uranium. He referred to the emitted rays as 'uranic rays', and was able to show that they could electrify the air.

This diagram shows a stationary box sitting on the floor. Which statements about the other force exerted on the box are
Alex777 [14]

It's a normal force exerted by the floor. It balances the gravitational force. Option A is correct. The normal force is balanced by the gravitational force.

<h3>What is the friction force?</h3>

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N). Mathematically it is defined as the product of the coefficient of friction and normal reaction.

On resolving the given force and accelertaion in the different components and balancing the equation gets components in the y-direction.

The normal force is balanced by the gravitational force. It's a normal force exerted by the floor. It balances the gravitational force.

Hence, option A is correct.

The first few steps in deriving the quadratic formula are shown. Which best explains why is not added to the left side of the eq
bija089 [108]
The term b^2 / 4a^2 is not added to the left side of the equation, because the term that was added to the right was not either b^2 / 4 a^2.

As you can see the ther b^2 / 4a^2 that appears in the last step of the table is inside a parenthesis, which is preceded by factor a.


Then, you need to apply the distributive property to know the term that you are really adding to the right side,  i.e. you need to mulitply b^2 / 4a^2 * a which is b^2 / 4a.


That means that you are really adding b^2 / 4a to the right, so that is the same that you have to add to the left, which is what the last step of the table shows.


That situation is reflected by the statement "<span>The distributive property needs to be applied to determine the value to add to the left side of the equation to balance the sides of the equation".</span>  That is the answer.

If the effort distance = 8 meters and the resistance distance = 1/2 meter. How much force does this man have to apply to lift th
Delicious77 [7]

Answer:

Explanation:

Effort x effort distance = load x resistance  distance

effort distance = 8 m ,

load = 2000N

resistance distance = 1/2 m = 0.5 m

Putting the values in the equation above

effort x 8m = 2000N x .5

effort = 2000 x 0.5 / 8

= 125 N

force required = 125 N .
