Transcripts
Slide 1

The centripetal constrain on an auto adjusting a bend on a level street is given by a) gravity b) erosion c) the motor d) the auto\'s brakes e) ordinary drive

Slide 2

On a "managed an account" turn, what is giving the centripetal compel on an auto? grating and pressure contact and gravity erosion and typical constrain rubbing just

Slide 3

The moon\'s mass is just 1.2% of the world\'s mass. With respect to the gravitational drive the earth applies on the moon, the gravitational constrain the moon applies on the earth is a) littler b) a similar c) more noteworthy d) relies on upon whether the moon is made of cheddar or not

Slide 4

The moon\'s mass is just 1.2% of the world\'s mass. The gravitational quickening the earth encounters contrasted with the gravitational speeding up the moon encounters is littler b) a similar c) more prominent

Slide 5

A basin on a water wheel with a sweep of 2.5 m makes one finish upset in 4.2 seconds. How quick is the can moving? a)7.48 m/s b)3.7 m/s c)2.6 m/s d)1.87 m/s v = d/t d = Circumference = 2 π r v = 2 π (2.5)/4.2 v = 3.7 m/s

Slide 6

A 0.5 kg ball moves around 40 cm in span at a speed of 4.0 m/s. Its centripetal speeding up is F = mv 2/r mama = mv 2/r a = v 2/r a = 4 2/.4 a = 40 m/s 2 a) 10 m/s 2 b) 20 m/s 2 c) 30 m/s 2 d) 40 m/s 2

Slide 7

If the mass of Sputnik was multiplied, by what variable would the compel change if it somehow happened to stay in a similar round circle? two circumstances more prominent four circumstances more prominent half as much one-fourth as much no change

Slide 8

Two little masses that are 10 cm separated draw in each other with a compel of 10 N. When they are 5 cm separated, with what drive will they draw in each other? (G = 6.67  10 - 11 Nm 2/kg 2 ) a) 5 N b) 2.5 N c) 20 N d) 40 N

Slide 9

A question moves in a round way. On the off chance that the range is multiplied while keeping the speed the same, then the centripetal compel must be: a) two circumstances more b) half as much c) four circumstances more d) one-fourth as much e) the same

Slide 10

A planet of mass 3  10 28 kg is in circle around a star with mass 3  10 30 kg. The sweep of the circle is 1.5  10 m. The speed of the planet in circle is a) 6.03  10 48 m/s b) 1.15  10 12 m/s c) 1.15  10 4 m/s d) 1.16  10 5 m/s

Slide 11

The speed of the planet from the past question is 1.16  10 5 m/s. What is the time of the planet\'s circle? a)8.12  10 5 s b)4.21  10 6 s c)3.23  10 3 s d)2.74  10 3 s

Slide 12

The sweep of the way of a question in consistent roundabout movement is multiplied. The centripetal compel required if its speed continues as before is a) half as incredible as it was before b) the same as before c) twice as extraordinary as before d) four circumstances as awesome as before

Slide 13

Consider a thrill ride doing a circle. What gives the centripetal constrain? Erosion Normal drive Tension Gravity

Slide 14

Consider an exciting ride at the highest point of a circle. What gives the centripetal compel? Erosion and Gravity Normal drive and Friction Tension and Normal Force Gravity and Normal Force Centripetal Force and Gravity
