Use the drop-down menus to complete the passage. A galvanometer detects by showing needle movement in . If the wires in this gal

vanometer are attached to the terminals of a battery, the compass needle will move and point to the wrapped coil of wire. If the wires to the terminal connections are switched, the needle will move and point in the direction. The movement of the needle can be altered and read incorrectly if there is a strong nearby.

A circuit contains a 12 volt battery and two 3 ohm bulbs in series. Calculate the current
OLEGan [10]

If there are two bulbs in series, and each bulb has

                                                   resistance = 3 ohms,

then their total resistance in series is 6 ohms. 

When the series pair of bulbs is connected across the terminals
of the battery, the current through the circuit is

 Current = (voltage) / (resistance) 

               =  (12 volts) / (6 ohms)  =  2 amperes

The tortoise and the hare are having a race over a course of length 0.52 km. The tortoise crawls along at a constant 0.075 m/s w
EastWind [94]

Answer:the hare slept for 1 hr 55minutes.

Explanation: distance is changed to meters = 520m

Speed=distance/time

Speed of tortoise is 0.075m/s=520m/t

Crops multiplying t= 520/0.075 = 6933.3 seconds.

Speed for hare 16.7m/s =260m/t

ie 260m is half of the distance.

t =15.56seconds

Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.

Converting to hours = 1hr. 55minutes is the time the hare slept.

The two forces of a 3rd law pair always act on different bodies. The two forces of a 3rd law pair always act on different bodies
svetoff [14.1K]

1. The two forces of a 3rd law pair always act on different bodies.

TRUE

SO above statement is TRUE because Newton's III law is valid for two different objects where one object will exert force and other body will exert reaction force on it.

2. Part F Given that two bodies interact via some force, the accelerations of these two bodies have the same magnitude but opposite directions. (Assume no other forces act on either body.)

FALSE

This is false because the force of action and Reaction is same on two different objects but for finding acceleration we need to divide the force by mass of two objects and since the mass of two bodies may be different so we can say that acceleration may be different.

3. Part G According to Newton's 3rd law, the force on the (smaller) moon due to the (larger) earth is

(i) greater in magnitude and antiparallel to the force on the earth due to the moon.

(ii) greater in magnitude and parallel to the force on the earth due to the moon.

(iii) equal in magnitude but antiparallel to the force on the earth due to the moon.

(iv) equal in magnitude and parallel to the force on the earth due to the moon.

(v) smaller in magnitude and antiparallel to the force on the earth due to the moon.

(vi) smaller in magnitude and parallel to the force on the earth due to the moon.

Since Earth and moon is an isolated system so here Newton's III law is valid due to which we can say that two forces are equal in magnitude but opposite in sign

so correct answer will be

equal in magnitude but antiparallel to the force on the earth due to the moon.

What is the centripetal force acting on a 1.5 kg mass moving in a circular path with a centripetal
zloy xaker [14]

The centripetal force acting on a 1.5 kg mass moving in a circular path is 27N

A centripetal force is a net force acting on an object in order to maintain the object's movement in a circular motion.

According  to Newton's first law, it states an object will continue to proceed its movement in a straight line unless acted upon by an external force.

The centripetal force is the external force at work here and  It's the net force that propels the object in a circular motion.

Using the formula for calculating centripetal force:

\mathbf{F_c = mass (m) \times acceleration (a)}

\mathbf{F_c = 1.5 \ kg \times18 \ m/s^2}

\mathbf{F_c = 27 \ N}

What is the force on a 1670kg elevator accelerating at 6m/s square?
marshall27 [118]

As per Newton's 2nd law

we know that

F = ma

it is product of mass and acceleration

here we know that

m = 1670 kg

also we know that

a = 6 m/s^2

so from above equation we have

F = 1670 * 6

F = 10020 N

so the force here will be 10020 N
