How would you change the distance between two positively charged particles if the distance is increased by a factor of 2?a. it is decreased by a factor of 2
b. it is increased by a factor of 2
c. it is increased by a factor of 4
d. it is decreased by a factor of 4

Answers

Answer 1
Answer:

Answer:

D, it would decrease by a factor of 4

Explanation:

We know the force between two charged particles, also known as Coulombs law.

F = (kq_(1)q_(2))/(r^2)

We are only changing the distance, not the charges, so we can ignore both q and look at r, which is the distance between the two positively charged particles.

So let F be our initial condition:

F \alpha (1)/(r^2) \nF' \alpha  (1)/((2*r)^2) = (1)/(4*r^2)\nF' = (1)/(4) *F

So the answer is D, it decreases by a factor of 4.

Suppose for your cookout you need to make 100 hamburgers. You knoe that 2.00 pounds will make 9 hamburgers. How many pounds will u need?

Answers

The cook needs to make 100 hamburgers. The price of 9 hamburgers is 2 pounds. Then 22.2 pounds are needed to bring 100 hamburgers.

What are methods of finding price values ?

There are simple mathematics to find the price of a material based on the data we have on it. For example if we know the price of one unit of that material then multiply the price by the number of units we want to buy.

If know the price of a bulk or certain number of materials, then find the price of one material from it.

Here, the price of 9 hamburgers is given 2 pound. Then, the price of one hamburger is :

2/9 = 0.22.

Now, multiply the value of one hamburger with the number that we want. We want 100 hamburgers. Then,

100× 0.22 = 22.2 pounds.

Therefore, 22.2 pounds are needed for 100 hamburgers.

if 
2.0 pound will make 9 hamburgers 
so 100 hamburgers will make by pounds = 100/9 × 2.0 = 22.2 pounds

the ans is (22.22 pounds will make 100 hamburgers)

What is the difference between work done by fuel and work done by moving object??
​

Answers

Answer:

work done by fuel is chemical energy and work done by moving objects is kinetic energy

Explanation:

when work is done by object that object gains energy . when the work is done by an object that object loses energy because it is transferring it to something else .

Answer:

work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning

What is true about the inertia of two cars, Car A of mass 1,500 kilograms and Car B of mass 2,000 kilograms

Answers

Answer:

Car B

Explanation:

Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.

According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.

The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.
 Car B has more inertia then Car A
