A torque acts on a wheel rotating at 19.8 rad/s and increases its angular speed to 23.5 rad/s in 11.2 s. Find the angle through
faltersainse [42]

243 rad is the angle through which the wheel turns during this time.

<h3>What is torque and angular speed?</h3>

Torque is a measure of the force that can cause an object to rotate about an axis.

Angular speed is define as  the measuring angle of rotation over a given amount of time.

Mathematically , ω = θ t

From the given question ,

Torque = 19.8 rad/s

ω = 23.5 rad/s

t = 11.2 s

We get the equation,

\frac{ 19.8 +23.5}{2} * 11.2

= 243 rad

according to newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off.
Umnica [9.8K]

Unless acted upon by an external force, an object in motion tends to stay in motion, and an object at rest prefers to stay at rest.

We can also see that we regress when a car abruptly begins to move from a condition of rest. The inertia of repose also contributes to this. Our bodies have a tendency to stay in a condition of rest, but as soon as the automobile starts moving, we start to regress.

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. Second Law of Motion by Newton.

A sun-like star is barely visible to naked-eye observers on earth when it is a distance of 7.0 light years, or 6.6 * 1016 m, awa
igomit [66]

Answer:

At a distance of 1376.49 candle emits 0.2 watt power

Explanation:

Distance between Sun and earth 6.6\times 10^{16}m

Sun emits a power of P=3.8\times 10^{26}watt

Power emitted by candle = 0.20 watt

We know that brightness is given by

B=\frac{P}{4\pi d^2}

So \frac{3.8\times 10^{26}}{4\pi (6\times 10^{16})^2}=\frac{0.20}{4\pi d^2}

3.8\times 10^{26}d^2=7.2\times 10^{32}

d^2=1.89\times 10^6

d=1376.49m

So at a distance of 1376.49 candle emits 0.2 watt power
