It begins at the pinpoint with part vector 3.00 i ^ m. … with constant angular speed 1.50 rad/s in a circle of radius 3.00 m centered at the source.

<h3>How is the constant angular speed determined?</h3>

The angular velocity varies linearly at constant angular acceleration. As a result, for a given period, the average angular velocity is equal to half of the starting plus final angular velocity: -ω=ω0+ωf2. ω - = ω 0 + ω f 2 .

It is assumed that an object has a constant angular velocity when it moves in a circle at the same speed. As a result, when an object is traveling in an angular motion at the same speed, we can say that its angular velocity is constant.

Shear causes horizontal movement along a fault plane in a/n _______ fault. A. reverse
lakkis [162]
<span>The answer is B. Strike slip fault. Shearing occurs when plates or blocks of rocks slide past each other in the opposite direction. This occurs at transform plate margins. An example is the San Andreas Fault running through California, USA. Compression occurs at reverse faults and tension at normal faults. </span>

A ball rolls down an incline, starting from rest. if the total time it takes to reach the end of the incline is t, how much time
kirill [66]

A ball rolls down an inclined plane, starting from rest. if the total time it takes to reach the end of the inclined plane is t, how much time has elapsed when it is halfway down the incline 0.5t

An inclined plane is a straightforward device with a sloping surface that is used to lift heavy objects. When friction is taken into account, the force needed to move an object up an incline is less than the weight being raised. The needed force is closer to the real weight the higher the slope or incline.

The inclined plane is the most basic of all simple machines because nothing needs to move for it to function. In order to save effort, you have to move objects farther when using an inclined plane. A variety of techniques can be used to create an inclined plane. It can be as simple as a log leaning against a tree in the woods or a piece of wood placed on the edge of a stair.

A sphere has surface area 1.25 m2, emissivity 1.0, and temperature 100.0°C. What is the rate at which it radiates heat into empt
Yuri [45]
The total power emitted by an object via radiation is:
P=A\epsilon \sigma T^4
where:
A is the surface of the object (in our problem, A=1.25 m^2
\epsilon is the emissivity of the object (in our problem, \epsilon=1)
\sigma = 5.67 \cdot 10^{-8} W/(m^2 K^4) is the Stefan-Boltzmann constant
T is the absolute temperature of the object, which in our case is T=100^{\circ} C=373 K

Substituting these values, we find the power emitted by radiation:
P=(1.25 m^2)(1.0)(5.67 \cdot 10^{-8}W/(m^2K^4)})(373 K)^4=1371 W = 1.4 kW
So, the correct answer is D.
