A car is travelling at a velocity of 20m/s. After 30sec it covers a distance of 1200 m. Calculate the acceleration of the car an

Umnica [9.8K]

Answer:

Acceleration: $a = 1,3333 \frac{m}{s^{2} }$

Final velocity: $v = 60 \frac{m}{s}$

Explanation:

To calculate the acceleration, you start from the formula:

$s = v_i t+\frac{1}{2}at^{2}$

Thus:

$a = \frac{ 2(s - v_it)}{t^{2}}$

Now that you have the accelration, you can use the this formula to calculate the final speed:

$a = \frac{v_f - v_i}{\Delta t}$

Thus:

$v_f = a \Delta t + v_i$

What is paleomagnetism how has it been used to understand plate tectonics?

Nonamiya [84]

<span>Plate tectonics is the theory that the earth's crust is broken up into plates that float on top of a hotter and more fluid layer below. Evidence to support this theory has been uncovered through the study of the earth's past magnetic field, known as paleomagnetism.</span>

A 565 N rightward force pulls a large box across the floor with a constant velocity of 0.75 m/s. If the coefficient of friction

alukav5142 [94]

The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.

Three identical resistors are connected in parallel to a battery. If the current of 12. A flows from the battery, how much curre

Doss [256]

Answer:

4 A

Explanation:

We are given that

$R_1=R_2=R_3=4\Omega$

I=12 A

We have to find the current flowing through each resistor.

We know that in parallel combination current flowing through different resistors are different and potential difference across each resistor is same.

Formula :

$\frac{1}{R}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}$
