The correct answer is option B. i.e. 60 ohm.
The diagram is attached.

Since all the resistances are attached in series.
Hence, the total resistance will be the sum of all resistances.

R_total = R_1+R_2+ R_3
= 10+20+30
= 60 ohms.

Therefore, option c is correct answer.

The belt of one ramp moves at a constant speed such that a person who stands still on it leaves the ramp 64 s after getting on.
Bad White [126]

Answer:

0.74 m/s

Explanation:

given,

time taken by the ramp to cover cliff , t = 64 s

acceleration = 0.37 m/s²

distance traveled by the belt

 x = v_{belt}t_{belt}

Clifford  is moving with constant acceleration

 x = v_ot + \dfrac{1}{2}at^2...(1)

initial velocity is equal to zero

 x =\dfrac{1}{2}at^2........(2)

equating equation (1) and (2)

v_{belt}t_{belt}=\dfrac{1}{2}at^2

v_{belt}t_{belt}=\dfrac{1}{2}a(\dfrac{1}{4}\times t_{belt})^2

v_{belt}=\dfrac{1}{32}a t_{belt}

v_{belt}=\dfrac{1}{32}\times 0.37 \times 64

v_{belt}= 0.74\ m/s

Speed of the belt is equal to 0.74 m/s

Which equation best describes the law of conservation of momentum?
NeX [460]
The law of conservation of momentum<span> states that for two objects colliding in an isolated system, the total </span>momentum<span> before and after the collision is equal. Momentum should be conserved. Hope this answers the question. Have a nice day.</span>

You are pulling your little sister on her sled across an icy (frictionless) surface. When you exert a constant horizontal force
Tpy6a [65]

Answer:

Mass of Little Sister = 44.17 kg

Explanation:

From Newton's second law of motion, the magnitude of force applied on the sled is given by the following formula:

F = ma

where,

F = Force Applied = 120 N

a = Acceleration = 2.3 m/s²

m = Mass of Sled + Mass of Little Sister = 8 kg + Mass of Little Sister

Therefore,

120 N = (2.3 m/s²)(8 kg + Mass of Little Sister)

(120 N)/(2.3 m/s²) = 8 kg + Mass of Little Sister

Mass of Little Sister = 52.17 kg - 8 kg

<u>Mass of Little Sister = 44.17 kg</u>

A boy is whirling a stone around his head by means of a string. The string makes one complete revolution every second; and the m
Damm [24]

Answer

given,                                                

Tension of string is F                                                  

velocity is increased and the radius is not changed.      

the string makes two complete revolutions every second

consider the centrifugal force acting on the stone          

  = \dfrac{mv^2}{r}                          

now centrifugal force is balanced by tension

T =\dfrac{mv^2}{r}                                

From the above expression we can clearly see that tension is directly proportional to velocity and inversely proportional to radius.

When radius is not changing velocity is increasing means tension will also increase in the string.
