</h2><h3>kinetic energy is given as</h3>
KE = (0.5) m v²
given that : v = speed of the bottle in each case = 4 m/s when m = 0.125 kg
KE = (0.5) m v² = (0.5) (0.125) (4)² = 1 J
when m = 0.250 kg KE = (0.5) m v² = (0.5) (0.250) (4)² = 2 J
when m = 0.375 kg KE = (0.5) m v² = (0.5) (0.375) (4)² = 3 J
when m = 0.0.500 kg KE = (0.5) m v² = (0.5) (0.500) (4)² = 4 J
Answer:
Smallest collector size≈30
Explanation:
Daily sunlight intensity = 1400.
For a collector of 24% efficiency, the absorption per day per
= 0.24*1400 = 336.
For 8 hours, 25days of available sunlight, energy absorbed by collector per metre square , will be = 8* 25 *336 = 67200wh.
This is the amount of sunlight energy which will be trapped by 1. of collector in a month.
To find how many metre square of collector is required to get 2*kwh, we simply divide the required energy by the amount absorbed per square metre.
Smallest size of collected needed =
=29.76
≈30

The kinetic energy of the vehicle should be such it balances the centripetal and centrifugal forces whereas coming into and crossing the curve. whereas coming into, the driving force ought to scale back speed by gently persist brakes, till apex purpose has been reached. this can be the nearest purpose of the car to the within of curve line. Once that has been reached, accelerator ought to be gently pressed to use some force to pull the car<span> out of the curve.
Explanation:
He should slowly slow down the speed
</span>The brake is hard<span> as </span>potential in the<span> entry to the curve, then with less force as </span>you start<span> turning. The slowest </span>purpose ought to<span> be at the apex of the curve, </span>once that you're fast once more.
<span>Your tires have a limit to their grip before they slip (skid). </span>the concept<span> is to manage the forces on them. The </span>additional<span> lateral force from the </span>turn there's<span>, the less linear force </span>you'll<span> use braking or </span>fast.
<span>This is why corners </span>are<span> the passing zones on the track. If </span>you'll<span> out-brake </span>the opposite<span> guy going into the </span>flip<span>, </span>you'll<span> be </span>quicker within the turn, however<span> brake too late and </span>you will not<span> be </span>ready to flip while not<span> skidding.</span>
By formula, Kinetic Energy is:
<span>mass of the body time (the </span>speed<span> of the body) </span>everywhere two.
The mass of the body remains constant.
<span>Velocity is variable.</span>
