A wedge is one of the six simple machines. It is characterized by an object that has a defined width at one side that slopes to a point at the other end. This simple machines allows a force that is applied over a large area to be concentrated upon an edge or smaller area, such as a knife. This concentration of force is the mechanical advantage (MA) the wedge provides. Each of the six simple machines offers a mechanical advantage, and it can be quickly calculated for a wedge.SCIENCING

A wedge is one of the six simple machines. It is characterized by an object that has a defined width at one side that slopes to a point at the other end. This simple machines allows a force that is applied over a large area to be concentrated upon an edge or smaller area, such as a knife. This concentration of force is the mechanical advantage (MA) the wedge provides. Each of the six simple machines offers a mechanical advantage, and it can be quickly calculated for a wedge.



Find the length of the sloped surface of the wedge. For a real-world object, this can be found in by measuring with a tape measure or ruler. In the case of a math problem, this value is sometimes given. If it is not, it can be calculated using the Pythagorean Theorem (a^2)+(b^2)=(c^2) or the law of cosines (cos(a)/A)=(cos(b)/B)=(cos(c)/C)

Find the width of the large end of the wedge. This too can be found either by direct measurement or by mathematical calculation. Divide the slope length by the width of the wedge to find the mechanical advantage. MA=(Slope Length)/(Width)

TIP
Make sure that all lengths are in the same unit of measure.

<span>Angular velocity is the rate of the change of angular displacement of a body that is in a circular motion. It is a vector quantity so it consists of a magnitude and direction. It is equal to the linear velocity divided by the radius of the circular motion. However, we are not given the linear velocity and the radius of the motion. We instead use the equation for the rotational kinetic energy. It is expressed as:
</span>
Rotational kinetic energy = Iω^2 / 2

where I is the inertia and ω is the angular velocity

175 = (3.75)ω^2 / 2
ω = 9.66 rad/s

The angular velocity of the motion is about 9.66 rad / s.

Q2: Explain why looking up at the stars at night is like looking back in time.<br>​
Allushta [10]

Answer:

Explanation:

When you look at the stars at night, you are seeing light that may have taken 20 or 30 or even a few hundred years to reach your eyes. You are looking back in time. The distances in the universe are so vast that scientists use the term "light year" to measure them. So It takes much longer for their light to reach us.

A 1000watt microwave oven takes 90 seconds to heat a bowl of soup. How many joules of energy does it use?
Evgesh-ka [11]

Answer:

90000J

Explanation:

Given parameter:

Power of the microwave = 1000watt

time for soup to heat = 90s

Unknown:

Amount of energy delivered = ?

Solution:

Electric power is the rate at which electrical energy is transferred.

  Electrical power = \frac{electrical energy}{time}

 Electrical energy = electrical power x time

input the variables;

 Electrical energy = 1000 x 90 = 90000J
