On a hot sunny day, while playing on the ground our body temperature increases. Explain and define the process.

Explanation:

Its because of the sunlight being much hoter than your body absorbs the heat of the sun.

And its also because of aerobic respiration in which your body takes in oxygen and digests gluecose to creates energy(beacuse of any physical activity like, playing and stuff). So during the proscess in which uour body creates energy(energy-andenoisine triphosphate) HEAT is also created

Thus, your body fells hot during playing and in sunlight

Hope it helps

Also see my comment pls theres another answer.

Answer:

681.6/ms

Explanation:

A reconnaissance plane flies 545 km away from its base at 568 m/s. then flies back to its base at 852 m/s.

What is its average speed?

Answer in its of m/s

Avg speed of the round trip is

2*568*852/(568+852)= 681.6/ms

The parachute on a drag racing car deploys at the end of a run. If the car has a mass of 820 kg and the car is moving 36 m/s, wh

Lelechka [254]

In order to determine the required force to stop the car, proceed as follow:

Calculate the deceleration of the car, by using the following formula:

$v^2=v^2_o-2ax$

where,

v: final speed = 0m/s (the car stops)

vo: initial speed = 36m/s

x: distance traveled = 980m

a: deceleration of the car= ?

Solve the equation above for a, replace the values of the other parameters and simplify:

$\begin{gathered} a=\frac{v^2_o-v^2}{2x} \\ a=\frac{(36\frac{m}{s})^2-(0\frac{m}{s})^2}{2(980m)}=0.66\frac{m}{s^2} \end{gathered}$

Next, consider that the formula for the force is:

$F=ma$

where,

m: mass of the car = 820 kg

a: deceleration of the car = 0.66m/s^2

Replace the previous values and simplify:

$F=(820kg)(0.66\frac{m}{s^2})=542.20N$

Hence, the required force to stop the car is 542.20N

A force (5ỉ - ;)N moves an object from the point P (1,3) m to the point Q (3, 8) m.

natita [175]

Answer:

b) 5 J

Explanation:

Work is the energy transferred by an object when acted by a force along a displacement. Work is the product of force and displacement. The SI unit of work is the joules (J)

To calculate the work done by the force, we have to first get the displacement (D) of the object. Hence:

Displacement (D) = Q(3, 8) - P(1, 3) = (3 - 1, 8 - 3) = (2, 5) = 2i + 5j

The work done is the dot product of the force and the displacement. Force = 5i - j. Hence:

Work done = (5i - j)(2i + 5j) = 10 - 5 = 5 J
