Answer:
Explained
Explanation:
one side of the single magnet attracted the metal surface, but repelled the stack of magnets because magnet's both poles try to attract by inducing opposite pole on the metal surface,but the pole closer to the metal is able to induce more magnetic character .so, attractive force due to this is more strong as the distance is also less as compared to the other pole.
Answer:
Acceleration
Explanation:
The fact that new can go from zero to 60mph in 8 secs is a description of its pick-up or in physics, it's called acceleration.
Here initial velocity u= 0
final velocity v = 60 mph = 1m/minute.
or v =1609.344/60 = 26.82m/s
and time taken to do so is 8 sec
Acceleration a = (v-u)/t
a = (26.82-0)/8 = 3.35 m/s^2
Therefore, acceleration of the car a = 3.35 m/s^2.
-- <em>Mechanical waves DO</em> require a medium in order to travel from place to place. (Sound can't travel without some material to travel through on the way.)
-- <em>Electromagnetic waves do NOT</em> need a medium in order to travel from place to place. (Sunlight reaches us from the Sun without anything to travel through on the way.)
Your name, the amount of money in your pocket, and the mass of your body
both travel with you wherever you go, and don't depend on where you are.
Answer:
The frisky otters will be moving at the same speed at the bottom of the hill because the hillsides are of the same height
Explanation:
From the question we are told that
The slope of the hill of otter one is 
The slope of the hill of otter two is 
Generally the from the law of energy conservation
Here 
and 
So
=> 
From this equation for v we see that velocity is only dependent on the height and is not affected by the slope
Hence both frisky otters will travel at same speed because the hillsides are of the same height
