You can describe the _______________ of an object by saying it is moving in a straight line or is curved around another object.

You can also describe where an object is by its _______________ in relation to another object. The second object acts as a _______________ point. When an object changes position, you know it has motion. Motion can also be described by finding an object's _______________, or how fast or slow it moves in a certain amount of time. In addition, you can describe the object's speed AND direction together. This is called _______________.

Answer:

You can describe the<u> motion </u>of an object by saying it is moving in a straight line or is curved around another object. You can also describe where an object is by its <u> position </u> in relation to another object. The second object acts as a<u> reference</u> point. When an object changes position, you know it has motion. Motion can also be described by finding an object's <u>speed  </u>or how fast or slow it moves in a certain amount of time. In addition, you can describe the object's speed AND direction together. This is called <u>velocity</u>

Explanation:

In the given answer-

<u>Motion</u> is defined as - the change in the movement or position of any object  or body.

<u>Position</u> is said to be a place or somewhere or a location where any object or body is particularly placed/located or put on.

<u>Reference poin</u>t is a fixed point with regards to which any object or body changes its position. It is also called reference origin.

<u>Speed</u> is defined as the rate of any object covering certain distances. It is a scaler quantity (quantity which depends upon only magnitude).

<u>Velocity</u> is defined as the rate of speed per unit time. It is a vector quantity (quantity depending upon both magnitude and direction ).

As a bat flies toward a wall at a speed of 6.0 m/s, the bat emits an ultrasonic sound wave with frequency 30.0 kHz. What frequen
Leto [7]

Answer:

f_b = 29.98 Hz

Explanation:

speed of bat = 6 m/s

sound wave frequency emitted by bat = 30.0 kHz

as we know,

speed of sound (c)= 343 m/s

f_w = f(\dfrac{c+v_r}{c+v_s})

f_w = 30(\dfrac{343+0}{343+6})

f_w = 29.48 Hz

now frequency received by bat is equal to  

f_b = f(\dfrac{c+v_r}{c+v_s})

f_b = 29.48(\dfrac{343+6}{343+0})

f_b = 29.98 Hz

hence the frequency hear by bat will be 29.98 Hz

A tight knot can be easily opens by using a longer spanner. Give reasons
kobusy [5.1K]

It is because the effort distance is greater than the load distance

Explanation:

As we know, Effort×effort distance = load × load distance

So when effort distance is increases,

The effort decreases

So when the spanner’s handle is long

A tight knot can easily be opened by less effrot

An example of potential energy is a ball sitting _____ of the stairs.
expeople1 [14]

Answer:

at the top

Explanation:

Potential energy is the stored energy, mechanical energy,

or energy possessed by by virtue of the position of an object.an example of potential energy is the energy that a ball possesses by virtue of its sitting at the top of the stairs it being about to roll down the stairs.

In a real machine, the work output is always less than the work input.<br> a. True<br> b. False
Artist 52 [7]
<span>In a real machine, the work output is always less than the work input is true. The answer is letter A. it follows the law of entropy where no energy can be converted completely into work. Under this law, Carnot’s theorem states that Carnot’s engine can perform 100% of work. However, no such engine has ever succeeded the conversion of work into 100%. The greatest efficiency so far is at 80%.  Because there will always be factors that could affect the conversion of work. </span>
