<span>The car would have traveled exactly one-half of the circumference of the track, since it would have gone from one extreme point to its opposite extreme point. This would be equal to (3.5 / 2), or 1.75 km. The northernmost point would be 1.75km away from the southernmost point.</span>
Your question has been heard loud and clear.
An alpha particle , can move in any direction randomly. But with a magnetic field , we can deflect the alpha particle in any direction we want.
So , the magnetic field must be placed to the west of the alpha particle , so that the particle gets deflected and moves towards the north direction.
Thank you.
Answer:
B The resultant force on the satellite is towards the Earth.
Explanation:
In the case when the satellite orbits earth would be at constant speed in the circular orbit so hee the resultant force that on the satellite would be with regard to the earth
So as per the given situation, the option B is correct
And, the rest of the options would be wrong
And, the same would be relevant
The correct answer is D. 2200 Hz
Explanation:
The frequency of a wave is measured in hertz (Hz) and refers to how often a wave passes through a point during a specific time. This factor can be calculated if you divide the velocity of the wave by the wavelength (distance between crests) this means f (frequency) = v (velocity) / λ (wavelength).
f (frequency) = 242 m/s (velocity) / 0.11 (wavelegth)
f = 2200 Hz
According to this, the frequency of the wave, in this case, is 2200 Hz
Newton's 1st law of motion states that <span>an object at rest stays at rest and an object in uniform motion along a straight line stays in motion unless acted upon by an unbalanced force.
This law talks about the tendency of an object to resist any change in its state of rest or uniform motion, this is called Inertia. Thus Newton's 1st law of motion is also called the Law of Inertia</span>
