Answer : 'c' represent the 'Specific heat of substance'.

Explanation :

Specific heat : It is defined as the amount of heat required to raise the temperature of 1 kilogram of substance by one degree Celsius. The S.I unit of specific heat is, Joule per kelvin (J/K).

Formula for specific heat,

c=\frac{Q}{m\Delta T}

where,

c = specific heat capacity of substance

Q = heat required

m = mass of substance

\Delta T = change in temperature

Hence, 'c' represent the 'Specific heat of substance'.

KonstantinChe [14]

Answer:

d = 820 m

Explanation:

here we know that car starts from rest and continue to accelerate till it will reach to maximum speed of 20 m/s

so we will have

v_f - v_i = at

20 - 0 = 2t

t = 10 s

so car will accelerate till t = 10 then it will move with uniform speed

so the distance moved by the car till it accelerates is given as

d = \frac{1}{2}at^2

d = \frac{1}{2}(2)(10^2)

d_1 = 100 m

now it will move with uniform speed for next 36 s

so we have

d_2 = 20(36) = 720 m

so total distance moved by the car is given as

d = d_1 + d_2

d = 100 + 720

d = 820 m

Answer:

F = 17.3 kN

Explanation:

The normal force must support the weight of the car plus provide for the needed centripetal acceleration.

F = m(g + v²/R ) = 1000(9.8 + 15²/30) = 17,300

How does a battery work?
Flauer [41]

Answer:

Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
