Answer:

C. an interaction between a magnetic south pole and a north pole

Explanation:

  • According to the situation the magnetic properties of the fields of the south and the north by the nature of the electrically charged electromagnets. That exerts a force and likewise, the earth also has two magnetic poles that have positive and negative properties and both oppose the each other properties.

How far from the lens must the film in a camera be, if the lens has a 35.0 mm focal length and is being used to photograph a flo
Lemur [1.5K]

Answer:

The film in a camera be is placed at a distance of 3.67 cm.

Explanation:

Given that,

Focal length of the lens, f = +35 mm = +3.5 cm

Object distance of the flower, u = -75 cm

Using lens formula to find the distance from the lens must the film in a camera be. Using lens formula as :

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}\\\\\dfrac{1}{v}=\dfrac{1}{f}+\dfrac{1}{u}\\\\\dfrac{1}{v}=\dfrac{1}{(3.5)}+\dfrac{1}{(-75)}\\\\v=3.67\ cm

So, the film in a camera be is placed at a distance of 3.67 cm.

The cheetah, the fastest of land animals, can run a distance of 274 m in 8.65 s at its top speed. What is the cheetahs top speed
OverLord2011 [107]

Answer:

31.68 meters per second.

Explanation:

Speed is equals to Distance divided by Time, so, this means that speed is inversely proportional to time and directly proportional to distance.

Here, Distance is given which is 274 meters.

          Time taken to cover the given distance is 8.65 seconds.

So, by putting the values of distance and time in the formula of speed we will get the top speed of Cheetah which is 31.68 meters per second.

A 69 g particle is moving to the left at 25 m/s . How much net work must be done on the particle to cause it to move to the righ
LekaFEV [45]

Answer:11.59 J

Explanation:

Given

mass of Particle m=69 gm

Initially Particle moves towards left v_1=25 m/s

Final velocity of Particle is towards Right v_2=31 m/s

According to Work Energy theorem

Work done by all the Forces=change in Kinetic Energy

Work done by Force=\frac{mv_2^2}{2}-\frac{mv_1^2}{2}

W=\frac{69\times 10^{-3}}{2}\left [ 31^-25^2\right ]

W=\frac{69\times 10^{-3}}{2}\left [ 961-625\right ]

W=11.59 J
