It will move away from the large ball because like charges repel.

Explanation:

Because both of them are "like" charges they will repel and so the other answers are wrong

Answer:

It will move away from the large ball because like charges repel.

Explanation:

Electric force is the force that pushes apart two like charges, or that pulls together two unlike charges. The basic law of electrostatics Like charges of electricity repel each other, whereas unlike charges attract each other. When small, positively charged ball is moved close to a large, positively charged ball it would be pushed away from the large positively charged ball since they are both positively charged. One has to put in energy to try to move the small ball closer to the large ball. The closer one try to move it to the large ball, the more energy one has to put in, so the more electrical potential energy the small ball would have.

Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and

lorasvet [3.4K]

Answer: One canister contains 1.03 Kg of fuel,

Explanation:

The density is defined as the relation between the mass and the volume $p=\frac{m}{v}$

First of all you need to have the same units for volume and density, so:

For the volume,

$1.45 L * \frac{1.10*10^{-3}m^{3} }{1 L} = 1.45 *10^{-3} m^{3}$

For the density,

$p = 0.710\frac{g}{cm^{3} } *\frac{1cm^{3} }{1*10^{-6}m^{3} }*\frac{1 Kg}{1*10^{3}g } = 710\frac{Kg}{m^{3} }$

From the density equation we have $m=p*v$ , so:

$710\frac{Kg}{m^{3} } *1.45*10^{-3} m^{3} = 1.03Kg$

GarryVolchara [31]

newton 1st law: w no external force, a body will stay at rest or in constant uniform motion.

a motor raises the car up the tower. cuz it moves w/ constant vel, there is no external force: the motor force is the same n in opposity direction as the gravity force on car.

Skateboard A Force: 33 N Time: 0. 12 s Skateboard B Force: 33 N Time: 0. 57 s Skateboard C Force: 33 N Time: 0. 78 s Which skate

Snowcat [4.5K]

The skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)

From the question,

We are to determine which skateboard has the greatest impulse. To do this, we will calculate the impulse of each skate board.

Impulse can be calculated by using the formula

I = Ft

Where I is the impulse

F is the force

and t is the time

For Skateboard A

Force = 33 N

Time = 0. 12 s

∴ Impulse = 33 × 0.12

Impulse = 3.96 Ns

For Skateboard B

Force = 33 N

Time = 0. 57 s

∴ Impulse = 33 × 0.57

Impulse = 18.81 Ns

For Skateboard C

Force = 33 N

Time = 0. 78 s

∴ Impulse = 33 × 0.78

Impulse = 25.74 Ns

Hence, the skateboard that has the greatest impulse is Skateboard C (Impulse = 25.74 Ns)
