The correct answer is:

An apple falling from a tree is transitional kinetic energy

Explanation:

The energy of motion of a body, according to the work it would do if it were produced to rest. The translational kinetic energy depends on motion through space, and for a determined body of regular mass is equal to the output of half the mass times the intersection of the speed. and translational (the energy due to a motion from one position to another.

Answer: Option (e) is the correct answer.

Explanation:

There are three types of kinetic energy which are vibrational, rotational and translational kinetic energy.

A plucked string on a guitar will produce sound and it represents vibrational kinetic energy.

The moving blades of a ceiling fan shows the rotation of blades and it represents rotational kinetic energy.

A spinning top also displays rotation therefore, it represents rotational kinetic energy.

A tuning fork struck on a rubber block will produce sound and it will vibrate. Therefore, it represents vibrational kinetic energy.

An apple falling from a tree shows that apple is linearly falls on the ground therefore, it represents translational kinetic energy.

Thus, we can conclude that an apple falling from a tree is the best example which represents translational kinetic energy.

It makes the data thet they collect more reliable so if they need the data again, they have already tested it a few times so therefor they know that it is right.

Why would knowing the characteristics of circuits be important in designing electrical circuits?

zubka84 [21]

Well if you didn't you could make mistakes, which would lead ,in the best case, at a fail of the circuit , or if it goes out of control it could be dangerous

for example you have to know that the wires become hot and they loose their abbilitys as connecters(the hotter it will, the more energy you lose becouse the R will be bigger)

A certain unfiltered full-wave rectifier with 120 V, 60 Hz input produces an output with a peak of 15 V. When a capacitor-input

KATRIN_1 [288]

Answer:

The peak-to-peak ripple voltage = 2V

Explanation:

120V and 60 Hz is the input of an unfiltered full-wave rectifier

Peak value of output voltage = 15V

load connected = 1.0kV

dc output voltage = 14V

dc value of the output voltage of capacitor-input filter

where

V(dc value of output voltage) represent V₀

V(peak value of output voltage) represent V₁

V₀ = 1 - ( $\frac{1}{2fRC}$ )V₁

make C the subject of formula

V₀/V₁ = 1 - (1 / 2fRC)

1 / 2fRC = 1 - (v₀/V₁)

C = 2fR ((1 - (v₀/V₁))⁻¹

Substitute for,

f = 240Hz , R = 1.0Ω, V₀ = 14V , V₁ = 15V

C = 2 * 240 * 1 (( 1 - (14/15))⁻¹

C = 62.2μf

The peak-to-peak ripple voltage

= (1 / fRC)V₁

= 1 / ( (120 * 1 * 62.2) )15V

= 2V

The peak-to-peak ripple voltage = 2V

3. A lady walks 15.0 meters east and then 20.0 meters north.

NemiM [27]

Answer:

a. 25m

b. 25m

c. 35m

Explanation:

Given the distances walked as 15m east and 20m north:

Using Pythagoras Theorem, we calculate displacement as:

$a^2+b^2=c2, a=15,b=-20\\\\15^2+20^2=c^2\\\\c=\sqrt{15^2+20^2}=\sqrt{625}\\\\c=25m$

Hence, the resultant displacement is 25m

b. The distance from her start point is obtained by drawing a straight line from her final point to her initial point.

Given the distances walked as 15m east and 20m north:

Using Pythagoras Theorem, we calculate displacement as:

$a^2+b^2=c2, a=15,b=-20\\\\15^2+20^2=c^2\\\\c=\sqrt{15^2+20^2}=\sqrt{625}\\\\c=25m$

Hence, she is 25m away from her starting point.

c. The distance traveled is calculated by summing the total distance walked:

$d=d_1+d_2\\\\=15+20\\\\=35m$

Hence, the total distance traveled is 35m
