Answer:

Explanation:

The law of inertia states that if an object is in motion will remain in motion unless an external force is applied to it.

law of inertia for the rotating system in terms of angular momentum states that the angular momentum of a system will remain the same unless an external torque is applied to the system.

External Torque either increases or decreases the angular velocity thus changing angular momentum.

erik [133]

Answer:

$P = 36068.7 Watt$

Explanation:

As we know that average power is the ratio of total work done and total time interval

so we will have

$Power = \frac{Total \: Work}{time}$

now we know that

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

$W = \frac{1}{2}(700)(11^2) + 700(9.8)(9.6)$

so we will have

$W = 42350 J + 68856 J$

$W = 108206 J$

now power is given as

$P = \frac{108206}{3}$

$P = 36068.7 Watt$

In a carnival booth, you can win a stuffed giraffe if you toss a quarter into a small dish. the dish is on a shelf above the poi

Georgia [21]

components of the speed of the coin is given as

$v_x = v cos60$

$v_x = 6.4 cos60 = 3.2 m/s$

$v_y = vsin60$

$v_y = 6.4 sin60 = 5.54 m/s$

now the time taken by the coin to reach the plate is given by

$t = \frac{\delta x}{v_x}$

$t = \frac{2.1}{3.2}$

$t = 0.656 s$

now in order to find the height

$h = vy * t + \frac{1}{2} at^2$

$h = 5.54 * 0.656 - \frac{1}{2}*9.8*(0.656)^2$

$h = 1.52 m$

so it is placed at 1.52 m height

How long does it take to produce a star?

Reika [66]

Answer: From the moment the first gas cloud begins to compress until the star is formed and glows like the Sun, the process of star creation takes around a million years. Planets and other objects circle the central star using the remaining material from the star's formation.
