Answer:

Heat capacity, Q = 2090 Joules.

Explanation:

Given the following data;

Mass = 100 grams

Specific heat capacity = 4.18 J/g°C.

Temperature = 5°C

To find the quantity of heat required;

Heat capacity is given by the formula;

$Q = mct$

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

t represents the temperature of an object.

Substituting into the formula, we have;

$Q = 100*4.18*5$

Heat capacity, Q = 2090 Joules.

Answer:

240 kPa

Explanation:

The ideal gas law states:

$pV=nRT$

where

p is the gas pressure

V is the gas volume

n is the number of moles

R is the gas constant

T is the absolute temperature of the gas

For a fixed amount of gas, n and R are constant, so we can rewrite the equation as

$\frac{pV}{T}=const.$

For the gas in the problem, which undergoes a transformation, this can be rewritten as

$\frac{p_1V_1}{T_1}=\frac{p_2V_2}{T_2}$

where we have:

$p_1 = 98 kPa=9.8\cdot 10^4 Pa$ is the initial pressure

$V_1 = 750 mL=0.75 L=0.75\cdot 10^{-3} m^3$ is the initial volume

$T_1 =30^{\circ}C =303 K$ is the initial temperature

$p_2$ is the final pressure

$V_2=250 mL=0.25 L=0.25\cdot 10^{-3} m^3$ is the final volume

$T_2=-25^{\circ}C=248 K$ is the final temperature

Solving the formula for p2, we find the final pressure of the gas:

$p_2 = \frac{p_1 V_1 T_2}{T_1 V_2}=\frac{(9.8\cdot 10^4 Pa)(0.75\cdot 10^{-3}m^3)(248 K)}{(303 K)(0.25\cdot 10^{-3} m^3)}=2.4\cdot 10^5 Pa = 240 kPa$

A 800N student does a handstand with both hands at an angle of 15 degrees from the vertical what is the force on each hand

jeyben [28]

here we can say that net force on the student vertically upwards will be counter balance by his weight downwards

Let net force F is exerted by each hand

so here we will have

$2Fcos15 = W$

$2F cos15 = 800$

$F = \frac{800}{2 cos15}$

$F = 414.1 N$

so the force exerted by each hand will be 414.1 N
