If your vehicle sinks in water, which window should you kick out when the pressure equalizes?

<span>If your vehicle sinks in water and assuming that you are the driver, you should kick out the driver's window when the pressure equalizes.

You should't waste your time trying to reach the rear window and you shouldn't break the front window. Therefore, just break the one nearest to you which is the driver's window in this case.</span>

Some examples of solar ejections

mylen [45]

Coronal Mass ejections or Solar ejections are activities on the surface of the sun termed to the reaction of the gas composition of the sun's surface attributing to explosion of these gases. One example most commonly known as Solar Flares, and another example is termed as erupting prominence.

A solid ball of mass M = 2.0 kg and radius R = 0.25 m starts from rest at a height h = 3.0 m above the bottom of the path. It ro

Lady bird [3.3K]

Answer:

6.48 m/s

Explanation:

We are given that

Mass,M=2 kg

Radius,R=0.25 m

Height,h=3 m

Moment of inertia of solid sphere= $I=\frac{2}{5}MR^2$

We have to find the linear speed.

$\omega=\frac{v}{R}$

By law of conservation of energy

$mgh=\frac{1}{2}I\omega^2+\frac{1}{2}mv^2$

$mgh=\frac{1}{2}I(\frac{v}{R})^2+\frac{1}{2}mv^2=\frac{1}{2}v^2(\frac{I}{R^2}+m)$

Where $g=9.8m/s^2$

Substitute the values

$2\times 9.8\times 3=\frac{1}{2}(\frac{2}{5R^2}MR^2+M)=\frac{7}{10}Mv^2=\frac{7}{10}(2)v^2$

$v^2=\frac{2\times 9.8\times 3\times 10}{7\times 2}$

$v=\sqrt{\frac{2\times 9.8\times 3\times 5}{7}}$

$v=6.48m/s$

You are pushing a 60 kg block of ice across the ground. You exert a constant force of 9 N on the block of ice. You let go after

kotykmax [81]

Answer: d = 33 cm or 0.33 m

Explanation: In physics, Work is the amount of energy transferred to an object to make it move. It can be expressed by:

W = F.d.cosθ

F is the force applied to the object, d is the displacement and θ is the angle formed between the force and the displacement.

For the ice block, the angle is 0, i.e., force and distance are at the same direction, so:

W = F.d.cos(0)

W = F.d

To determine d:

d = $\frac{W}{F}$

d = $\frac{3}{9}$

d = 0.33 m

The distance d the block ice moved is 33 cm.
