Answer:

5 billion years

Explanation:

A star like the Sun is called a main sequence star. It is considered as young age star. Sun is a medium sized star and its mass determines how long it can continue in its present form.

Its heat and light are a result of the thermonuclear fusion reactions that occur in its core. The proton cycle and carbon cycle are responsible for generating the immense energy which is released in the form of heat and light. The amount of nuclear fuel ( hydrogen helium) present in the sun indicate that it can continue glowing at this state for another 5 or 5.5 billion years more. Sun formed abut 4.6 or 5 billion years ago, as shown from the calculations.

Answer:

Graph B represents correct graph for velocity time

Explanation:

Initially the object is dropped under the influence of constant force due to gravity

So here we can say its acceleration is constant due to gravity

hence here the velocity will increase downwards due to gravity and it is given as

$v = 0 + (-10)t$

now when it enters into the pool an upward force of same magnitude will act on it

so net force on it is

$F = 50 - 50 = 0$

so here we will have no acceleration and it will move with constant speed after that

so here correct graph is

Graph B

A sanding disk with rotational inertia 6.5 x 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of magnit

xeze [42]

Answer:

The angular momentum and angular velocity are 1.134 kg.m²/s and 174.5 rad/s.

Explanation:

Given that,

Moment of inertia $I= 6.5\times10^{-3}\ kg.m^2$

Torque = 21 N.m

Time dt = 54 ms

(a). We need to calculate the angular momentum

Using formula of torque

$\tau=\dfrac{dL}{dt}$

$dL =\tau\times t$

Where, dL = angular momentum

t = time

$\tau$ = torque

Put the value into the formula

$dL=21\times0.054$

$dL=1.134\ kg.m^2/s$

(b). We need to calculate the angular velocity of the disk

Using formula of angular velocity

$dL=I\omega$

$\omega=\dfrac{dL}{I}$

$\omega=\dfrac{1.134}{6.5\times10^{-3}}$

$\omega=174.5\ rad/s$

Hence, The angular momentum and angular velocity are 1.134 kg.m²/s and 174.5 rad/s.
