Q = heat energy , m=mass , c=specific heat , delta T= change in temperature

as you know heat is a form of energy which is <em>usually</em> measured in Joules according to the SI. and also we usually use kilograms for mass.

so you need to know the mass, specific heat, and change in temperature in order to find out the heat energy :)

Q is the quantity of heat energy used to change the temperature of specific mass of certain matter
M is the mass of matter u wanna to change its temperature
C is the specific heat, each substance has its own "C" as specific heat is the quantity of heat to change mass of 1 kg by 1 kalvin deg.
ΔT is the the difference in temp. from and to how much u wanna to change the temp. of your matter
so if u wanna to change 1L water (for example) which = to 1kg
u wanna to increase its temp. by 2 degrees
and the "c" is ≈ 4200 then
the quantity of energy u need to do that is = MCΔT = 1*4200*2 = 8400

An object slides down a frictionless inclined plane. At the bottom, it has a speed of 9.80 m/s. What is the vertical height of t

Papessa [141]

The vertical height of the given plane is 4.9 m.

The given parameters:

<em>speed of the object at the bottom of the ramp, v = 9.8 m/s</em>

The vertical height of the plane is calculated by applying principle of conservation of mechanical energy as follows;

$P.E = K.E\\\\mgh = \frac{1}{2} mv^2\\\\h = \frac{v^2}{2g} \\\\h = \frac{9.8 \times 9.8}{2 \times 9.8} \\\\h = 4.9 \ m$

Thus, the vertical height of the given plane is 4.9 m.

La corriente en un circuito se triplica conectando una R1 = 500 Ω en paralelo con la resistencia R del circuito. Determinar R en

Alexxx [7]

Answer:

R = 1000 ohm

Explanation:

In a circuit with a resistor R, the current is

V = i R

i₀ = V / R

a resistor R₁ is placed in parallel and the current is tripled i = 3 i₀

V = i Req

i = V / Req

3i₀ = V / Req

we substitute

3 (V / R) = V / Req

3 / R = 1 / Req

R = 3 Req

the equivalent resistance of the two resistors in parallel is

$\frac{1}{R_{eq}} = \frac{1}{R} + \frac{1}{R_1}$ $\frac{1}{R_{eq}} = \frac{R_1 + R}{R \ R_1}$

R_{eq} = $\frac{R \ R_1}{R + R_1}$

R / 3 = \frac{R \ R_1}{R + R_1}

⅓ (R₁ + R) = R₁

R = 3R₁ -R₁ = 2 R₁

R = 2 500

R = 1000 ohm

Mike understands the formula for temperature conversion, but is having difficulty imagining what various temperatures feel like.

Alisiya [41]

A good example that will help to to tell mike what 37°c feels like is body temperature.

<h3>What is room temprrature?</h3>

The average room temperature is typically around 20°C, or 68 degrees Fahrenheit.

<h3>What is body temperature?</h3>

The average body temperature is 98.6 Fahrenheit or 37 degrees Celsius.

Thus, a good example that will help to to tell mike what 37°c feels like is body temperature.
