4.5m/s you count the number between 6 and 14 and get 9 do 9 divided by 2 and you get 4.5 m/s increase. hope this helps.

The y-component of a projectile’s velocity is 12.1 m/s. When the projectile once again passes by the height from which it was la

Nat2105 [25]

It's 12.1 m/s, assuming that's the launch velocity that's given.
For projectile motion, velocity's y-component is parabolic/quadratic. It's x-component is constant, so you don't need to know it.

What is a nebula? please help I am clueless

Rainbow [258]

A nebula is gas, dust, and other things that form and form some sort of clould like thing. It also looks cool because of the colors it produces. I'm sure you could do a web search to find more about it, I don't take astronomy hahaha

A 0.50 kg object is attached to a spring with force constant 157 N/m so that the object is allowed to move on a horizontal frict

Genrish500 [490]

Explanation:

We have,

Mass of an object is 0.5 kg

Force constant of the spring is 157 N/m

The object is released from rest when the spring is compressed 0.19 m.

(A) The force acting on the object is given by :

F = kx

$F=157\times 0.19\\\\F=29.83\ N$

(B) The force is simply given by :

F = ma

a is acceleration at that instant

$a=\dfrac{F}{m}\\\\a=\dfrac{29.83}{0.5}\\\\a=59.66\ m/s^2$

What is the relationship between power and voltage?

kipiarov [429]

Answer:

The power and voltage are related through Power Rule .

Explanation :

Power Rule states that the current I that flows the element in the circuit with a loss in voltage V, then the amount of power dissipated by that element in the circuit is the multiplicative product of voltage and the current.

Mathematically, power law is

$\boldsymbol{P}=\boldsymbol{I} \times \boldsymbol{V}$

The rate of work done or the rate of energy consumption or production is termed as power.Unit of power is denoted as W(watts).

Potential energy between any two points on a circuit is called as Voltage and is measured in volts (V) .
