Calculate how much steam from water boiling at 100 C will just melt 50 gm of wax at 20 C. (Melting point of wax=55 C, sp. heat capacity of wax=0.7cal/g C, sp. latent heat of fusion of wax=35cal/g)
Answer:
m₁ = 5.507 x 10⁻³ kg = 5.507 g
Explanation:
The heat released by the steam must be absorbed by the melting wax, according to the law of conservation of energy:
Heat Released by Steam = Heat Absorbed by Wax
Latent Heat of Fusion of Steam = Heat Absorbed by Wax + Latent Heat of Fusion of Wax
m₁H₁ = m₂CΔT₂ + m₂H₂
where,
m₁ = mass of water = ?
H₁ = Latent Heat of Fusion of Water = 2260 KJ/kg = 2.26 x 10⁶ J/kg
m₂ = mass of wax = 50 g = 0.05 kg
C = specific heat capacity of wax = (0.7 cal/g°C)(1000 g/1 kg)(4.184 J/1 Cal)
C = 2928.8 J/kg.°C
ΔT₂ = Change in Temperature of Wax = 55°C - 20°C = 35°C
H₂ = Latent Heat of Fusion of Wax = (35 cal/g)(1000 g/1 kg)(4.184 J/1 Cal)
H₂ = 146440 J/kg
Therefore,
m₁(2.26 x 10⁶ J/kg) = (0.05 kg)(2928.8 J/kg.°C)(35°C) + (0.05 kg)(146440 J/kg)
m₁ = (5125.4 J + 7322 J)/2.26 x 10⁶ J/kg
m₁ = 5.507 x 10⁻³ kg = 5.507 g

The other name for 'net force' is 'unbalanced force'. What is the name of the force that could be applied to an object that would balance a net force and create a state of equilibrium?
Answer:
Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.

What is the force due to gravity of a 38 kg student?
Answer:
F_g = 372.78 N
Explanation:
Formula for force of gravity is;
F_g = mg
Where;
m is mass
g is acceleration due to gravity
We are given;
Mass = 38 kg
Acceleration due to gravity has a constant value of 9.81 m/s²
Thus;
F_g = 38 × 9.81
F_g = 372.78 N

PLEASE ANSWER
15. A 20-kilogram monkey hangs from a tree limb by both arms. Draw a free-body diagram showing the forces on the monkey. Hint: 20 kilograms is not a force!
Answer:
Farm = 98.1 [N]
Explanation:
To solve this problem we must draw the respective free body diagram, with the forces acting on the monkey. An analysis of the sums on the y-axis must be performed, in this axis the weight is acting down and the forces of both arms pulling up.
Weight is defined as the product of mass by gravitational acceleration.
W = m*g
where:
m = mass = 20 [kg]
g = gravity acceleration = 9.81 [m/s²]
W = 196.2 [N] (units of Newtons)
As this force points down, the force of both arms must go up, therefore each arm exerts a force of:
Farm = 196.2 / 2
Farm = 98.1 [N]

During exercise, the supply of oxygen and __________ to muscles increases. What one word completes the sentence?
Answer:
Glucose
Explanation:
During exercise, muscles need more energy. They get this energy by aerobic respiration, which uses oxygen and glucose to release energy.
Note: If the body fails to supply oxygen to the muscles fast enough, the muscles will produce energy by anaerobic respiration, which is not as effective as aerobic respiration in addition to producing lactic acid.
During exercise, the supply of oxygen and glucose to muscles increases. During exercise, muscles need more energy.
What happens during exercise?They get this energy by high-impact breath, which utilizes oxygen and glucose to deliver energy.
During exercise, your muscles are working diligently. Your breathing and pulse increment, maneuvering more oxygen into the circulation system. As you work out, the oxygen that arrives at your muscles changes over accessible glucose into ATP, furnishing your body with the energy it requires to finish your exercise.

If F applied is 17 Newtons to the right, what is the magnitude and direction of the friction force, if the object is traveling with the constant velocity?
Find friction force and its direction
There's some missing context here, but I would guess you're talking about a box or something with some mass m being pushed over a flat surface. Since it's moving with constant velocity, there is no acceleration and so the box is in equilibrium. In particular, the horizontal forces cancel each other. If f is the magnitude of the friction force, then
17 N + (-f ) = 0
f = 17 N
and this force points opposite the direction of motion.
A toy car is tied to a post with string, causing it to drive in a tight circle. This is
shown in the picture below.
In which direction will the toy car go if the string breaks?
Answer:the answer is direction b
Explanation:
If the string breaks, the toy car go on path B. The correct option is D.
What is centrifugal force?The pseudo force which acts when the centripetal force ceases to act on the particle moving in the circular path. While moving, the centripetal force acts towards the center of the circular path.
A toy car is tied to a post with string, causing it to drive in a tight circle. If the string breaks, the toy car is thrown out of the track.
The centrifugal force acts away from the center. But the velocity of motion will be tangential to the circular path. So, when string breaks, the toy car will follow the path B.
Thus, the correct option is D.
