An ocean current<span> is any more or less permanent or continuous, directed movement of </span>ocean<span> water that flows in one of the Earth's </span>oceans<span>. The </span>currents<span> are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.

You push very hard on a heavy desk, trying to move it. You do work on the desk:
frozen [14]

Answer:

(C) Only if it starts moving

Explanation:

We know that work done is given by

W=F.d=Fdcos\Theta

So there are two case in which work done is zero

First case is that when force and displacement are perpendicular to each other

And other case is that when there is no displacement

So for work to be done there must have displacement, if there is no displacement then there is no work done

So option (c) will be the correct option

Place any object (textbook, pen, or eraser) on a floor what happens then​
Levart [38]

Answer:

The force of gravity on earth, no matter the object is approximately 9.8 m/ s2 . The reason the crumpled paper hits the ground first is because of air resistance. A crumpled piece of paper has less surface area than an piece of paper that is not crumpled. More surface area means more air resistance.

A 1500 kg car decelerates from an initial velocity of 19 m/s to a skidding stop. If the coefficient of kinetic friction is 0.100
Stella [2.4K]

Answer:

19.4 seconds

Explanation:

We have:

m: mass of the car = 1500 kg

v₀: is the initial speed = 19 m/s    

v_{f}: is the final speed = 0 (it stops)

\mu_{k}: is the coefficient of kinetic friction = 0.100

First, we need to find the acceleration by using the second Newton's law:

\Epsilon F = ma              

-\mu_{k}N = ma

-\mu_{k}mg = ma

Solving for a:

a = -\mu_{k}g = -0.1*9.81 m/s^{2} = -0.981 m/s^{2}

Now we can find the time until it stops:

v_{f} = v_{0} + at

Solving for t:

t = \frac{v_{f} - v_{0}}{a} = \frac{-(19 m/s)}{-0.981 m/s^{2})} = 19.4 s

 

Therefore, the time until it stops is 19.4 seconds.

I hope it helps you!

Gold has a specific heat of 129 J/kg°C. How many joules of heat energy are required
ikadub [295]
To raise 1 kg by 1C, it will take 129 joules.

To raise 0.015 kg by (85-22)C, it will take (129*0.015)*22 = 42.57 joules.
