How do mass and speed affect kinetic energy?

1 answer:

7 0

The mass affects the kinetic energy because the more the mass the more energy is given to the object and the speed <span>affects it by making it go faster and longer, so whenever speed goes up so does energy.</span>

miv72 [106K]

It can't be less than 250 N or the cart wouldn't move at all. That means there is only 1 answer. It's between not enough info or 250 N. The answer is 250 N. If it was any more, there would be acceleration.

Tech A says parallel circuits are like links in a chain. Tech B says total current in a parallel circuit equals the sum of the c

rosijanka [135]

Answer: Only Tech B is correct.

Explanation:

First, tech A is wrong.

The circuits that can be compared with links in a chain are the series circuit, and it can be related to the links in a chain because if one of the elements breaks, the current can not flow furthermore (because the elements in the circuit are connected in series) while in a parallel circuit if one of the branches breaks, the current still can flow by other branches.

Also in a parallel circuit, the sum of the currents of each path is equal to the current that comes from the source, so Tech B is correct, the total current is equal to the sum of the currents flowing in each branch of the circuit.

On a bet, you try to remove water from a glass by blowing across the top of a vertical straw immersed in the water. What is the

MArishka [77]

Answer:

v₂ = 0.56 m / s

Explanation:

This exercise can be done using Bernoulli's equation

P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂

Where points 1 and 2 are on the surface of the glass and the top of the straw

The pressure at the two points is the same because they are open to the atmosphere, if we assume that the surface of the vessel is much sea that the area of the straw the velocity of the surface of the vessel is almost zero v₁ = 0

The difference in height between the level of the glass and the straw is constant and equal to 1.6 cm = 1.6 10⁻² m

We substitute in the equation

$P_{atm}$ + ρ g y₁ = $P_{atm}$ + ½ ρ v₂² + ρ g y₂
