A quantity that has magnitude only is a _____.
scalar
diagonal
vector

Answers

A quantity that has magnitude only is a scalar. In Physics, a quantity with only magnitude is called a scalar. Scalar quantities include distance, speed, mass, temperature, and energy. They are distinguished from vectors which have both magnitude and direction.

A scalar is a fundamental concept in mathematics and physics, representing a single quantity with magnitude but no direction. Scalars are characterized solely by their numerical value, such as speed or temperature. Unlike vectors, which have both magnitude and direction, scalars are concerned with the "how much" rather than the "where" or "in which direction." Scalars are used in various fields, from physics to mathematics and engineering, simplifying the description of quantities that don't involve direction, making calculations and analysis more straightforward.

A quantity that has magnitude only is referred to as a scalar. In Physics, quantities are typically classified into two types: scalars and vectors. A scalar quantity is defined by its magnitude alone, with no direction associated with it. Examples of scalar quantities include distance, speed, mass, temperature, and energy. On the contrary, a vector has both magnitude and direction. Hence, the correct answer to your question is scalar.

Answer:

scalar

Explanation:

Sound waves are produced by the horn of a truckthat is approaching a stationary observer.
Compared to the sound waves detected by the
driver of the truck, the sound waves detected by
the observer have a greater
(1) wavelength (3) period
(2) frequency (4) speed

Answers

Compared to the sound waves detected by the driver of the truck, the sound waves detected by the observer have a greater "(2) frequency" and will be more high pitched.

Answer: The correct option is (2).

Explanation:

Doppler effect is the phenomenon in which the frequency of the wave increase or decrease when there is relative motion between the source and the listener. There is an apparent change in the frequency.

When the source and the listener are approaching each other then there will be increase in the frequency.

When the source and the listener are moving away form each other then there will be decrease in the frequency.

In the given problem, Sound waves are produced by the horn of a truck

that is approaching a stationary observer. The sound waves detected by the observer have greater frequency.

Therefore, the correct option is (2).

How much work is done by a crane that lowers 1000N of material a distance of 150

Answers

The crane does NO work.

Work = (force) x (distance)

= (1,000 N) x (150 meters ?) = 150,000 joules

But the work is in the direction of the force, and it isn't the crane
pushing the material down. It's gravity.

Gravity is doing the work.

If the material was being lowered by a cable wrapped around the shaft
of an electric generator, then you could use the work done by gravity to
generate some electrical energy, and then sell the energy.

Or, if the "material" happened to be water, you could let gravity lower it
through a turbine or a water wheel, and use the work done by gravity to
grind wheat.

Yes, the crane may be raising a sweat, working against gravity. The
purpose is only to prevent gravityfrom doing the work too fast.

You step into an elevator on the 50th floor and it quickly accelerates downward. For a second, until steady speed is reached, __________. A.) your weight is unchanged but your mass decreases B.) your mass is unchanged but your weight decreases C.) neither your mass nor weight change but the gravitational force decreases D.) neither your mass nor weight change but your apparent weight decreases

Answers

Answer:

Mass and weight would stay the same. However, the normal force between the person and the ground becomes smaller, making the weight of the person appear smaller.

Explanation:

The mass of an object is an intrinsic property. The mass of the object stays the same regardless of the motion of the object or the forces acting on the object. As a result, when the elevator accelerates downwards, the mass of this person would stay the same.

The weight of an object refers to the gravitational force on this object.

The gravitational force on an object is the product of the mass $m$ and the strength $g$ of the gravitational field:

$(\text{weight}) = m\, g$ .

The gravitational field strength near the surface of the Earth is mostly uniform ( $g \approx 9.81\; {\rm N\cdot kg^(-1)}$ .) Since the mass of this person stays the same, the weight of this person would also stay the same.

When a person stands on level ground, forces on this person would include:

Weight, which points downward, and
Normal force from the ground, which points upward.

The net force on this person would be:

$(\text{net force}) = (\text{weight}) + (\text{normal force})$ .

Rearrange this equation to obtain an expression for normal force:

$(\text{normal force}) = (-(\text{weight})) + (\text{net force})$ .

When the person is not moving, acceleration of the person would be zero. By Newton's Laws of Motion, the net force on this person would also be zero.

In the equation above, the magnitude of the normal force would be equal to the magnitude of weight. It would appear that the normal force on the person is equal in magnitude to the weight of this person.

However, when the person accelerates in the vertical direction, the net force on the person will become non-zero in the vertical direction. Normal force would no longer be equal in magnitude to weight.

Specifically, when the person accelerates downward in this elevator, acceleration of this person would point downward. Net force on this person would also point downward.

In the equation $(\text{normal force}) = (-(\text{weight})) + (\text{net force})$ , $(\text{weight})$ also points downward. However, because of the negative sign $(-(\text{weight}))$ and $(\text{net force})$ would be in opposite directions.

Additionally, the magnitude of net force cannot exceed the magnitude of weight. As a result, the magnitude of the sum of these two vectors would be smaller than the magnitude of weight.

The normal force on this object is equal to the sum of these two vectors. As a result, the magnitude of normal force would also be smaller than the magnitude when the person isn't moving. It would appear as if the apparent weight of this person has become smaller than the original value.
