The volume should be 7.16 L
Boyles law:
Since there is a submarine with a volume of 1,510 liters has an internal pressure of 1.20atm. Also, there should be a pressure of 253atm pushing on it.
Here we used the Apply boyles law
So,
1510*1.20 = volume *253
So, the volume should be 7.16 L
hence, the volume is 7.16 L

A student attempted to measure the specific latent heat of vaporisation of water.
She took the following readings:
First balance reading (g) = 581
Second balance reading (g) = 526
First joulemeter reading (kJ) = 195
Second joulemeter reading (kJ) = 327
Use these results to determine the specific latent heat of vaporisation of water.
Answer:
The latent heat of vaporization of water is 2.4 kJ/g
Explanation:
The given readings are;
The first (mass) balance reading (of the water) in grams, m₁ = 581 g
The second (mass) balance reading (of the water) in grams, m₂ = 526 g
The first joulemeter reading in kilojoules (kJ), Q₁ = 195 kJ
The second joulemeter reading in kilojoules (kJ), Q₂ = 327 kJ
The latent heat of vaporization = The heat required to evaporate a given mass water at constant temperature
Based on the measurements, we have;
The latent heat of vaporization = ΔQ/Δm
∴ The latent heat of vaporization of water = (327 kJ - 195 kJ)/(581 g - 526 g) = 2.4 kJ/g
The latent heat of vaporization of water = 2.4 kJ/g

help pls physics problem
Answer:
0.4329 seconds
Explanation:
We are given;
Distance; d = 0.635 m
Velocity; v = 3.22 m/s
Angle; θ = 62.9°
To find the time, we have to find the horizontal component of the velocity.
Thus, Vx = 3.22 × cos 62.9
Formula for time is;
t = d/Vx
t = 0.635/(3.22 × cos 62.9)
t = 0.4329 sec
Thus the time he will take to clear the hurdle is 0.4329 sec
Strong magnetic fields created by high currents can result in:910 A. Arc flash B. Arc blast C. Large mechanical stresses that may cause conductors to move D. Shock
Answer:
B. Arc blast
Explanation:
Arc blast are as a result of rapid injection of electrical energy into an arc. These shock waves and arc blast pressure wave at low level can lead to damage of eardrums at lower levels and cardiac arrest at high levels.
Strong magnetic fields created by high currents (> 100 kA) can result to equipment destruction. These arc blast hazards are mostly found in high-energy power circuits and large capacitor banks.

A -0.6 C charge that moves downward is in a uniform electric field with a strength of 200 N/C what is the magnitude and direction of the force on the charge
Answer:
The magnitude and direction of the force on the charge is 120 N in the direction of the charge.
Explanation:
Given;
magnitude of the charge, q = 0.6 C
electric field strength, E = 200 N/C
The magnitude of the electric force is calculated as;
F = Eq
where;
F is the magnitude of the force
Substitute the given values and solve for F;
F = (200)(0.6)
F = 120 N in the direction of the charge.
Therefore, the magnitude and direction of the force on the charge is 120 N in the direction of the charge.
14. A 3.0 kg metal ball, at rest, is hit by a 1.0 kg metal ball moving at 4.0 m/s. The 3.0 kg ball moves
forward at 2.0 m/s and the 1.0 kg ball bounces back at 2.0 m/s.
(a) What is the total kinetic energy before the collision?
Answer:
The kinetic energy before the collision was 8 J
Explanation:
The given parameters are;
The mass of the metal ball at rest, m₁ = 3.0 kg
The velocity of the ball at rest = 0 m/s
The mass of the metal ball that hits the one at rest, m₂ = 1.0 kg
The velocity of the metal ball that hits the one at rest, v₂ = 4.0 m/s
The velocity with which the 3.0 kg ball moves forward = 2.0 m/s
The velocity with which the 1.0 kg ball bounces back = 2.0 m/s
a) Kinetic energy, K.E. = 1/2 × m × v²
Where;
m = The mass of the of the object in motion
v = The velocity of the object
Before the collision, we have;
Initial K.E. = 1/2 × m₁ × v₁² + 1/2 × m₂ × v₂²
∴ Initial K.E. = 1/2 × 3.0 kg × (0 m/s)² + 1/2 × 1.0 kg × (4.0 m/s) ² = 8 J
The kinetic energy before the collision = The initial K.E. = 8 J.

The level of mercury falls in a barometer
while taking it to a mountain.
Answer:
This is due to a relative decrease in atmospheric pressure in high places.
Explanation:
Given that atmospheric pressure decreases at the higher point or ground, this reduced atmospheric pressure, however, will be unable to contain the Mercury in the barometer tube.
Therefore, at the top of the mountain where the air pressure is low, the barometer reading ultimately goes down.
Hence, the level of mercury falls in a barometer while taking it to a mountain "due to a relative decrease in atmospheric pressure in high places."

An electric heater is rated at 1500 W. If the heater is rated as 80% efficient, calculate the output
rate of energy
Answer:
Power = 1200 [W].
Explanation:
The efficiency of an electrical equipment is defined as the relationship between the power realized, over the power that is consumed. For this case, they give us the data of consumed power and efficiency in this way we can calculate the power that the equipment performs.
[tex]Efficency=\frac{Power_{done}}{P_{consumed}}\\0.8 = \frac{Power_{done}}{1500} \\Power_{done}=1500*0.8\\Power_{done} = 1200 [W][/tex]
This means that of the 1500 [W], 1200 [W] are actually used to get the job done. This is established by means of the first law of thermodynamics.

What are the units of Mass and Weight in the English System? Explain.
Answer:
I tried...
Explanation:
Assuming the English system of mass and weight is the same as the Imperial system, the measurements are:
• 1 pound (lb) = 16 ounces (oz)
• 2,000 pounds (lbs) = 1 ton (T)
I think that's everything?
In the English system, mass is measured in pounds and weight is also measured in pounds. However, it is important to understand the difference between mass and weight.
Mass is a measure of the amount of matter in an object and is a scalar quantity. It does not change with location or gravitational force. In the English system, mass is typically measured using a scale or balance, which compares the object's mass to a standard mass. The pound (lb.) is the unit of mass in the English system.
Weight, on the other hand, is a measure of the force exerted on an object due to gravity and is a vector quantity. It depends on the object's mass and the gravitational force acting on it. In the English system, weight is typically measured using a spring scale or a balance that incorporates a spring. The pound (lb.) is also used as the unit of weight in the English system.
Weight = Mass x Acceleration due to gravity
Mass is measured in pounds (lb.) and weight is also measured in pounds (lb.).It is important to note that weight can vary depending on the gravitational force acting on an object.

PLEASE HELP! I know the answer to this, but I need an explanation.
Let r be the distance between the man and point Q. He applies a torque of
(r i ) × ((-800 N) j ) = ((-800 N) r ) k
pointing "into the page" with magnitude (800 N) r.
Meanwhile, the rope applies a torque of
((3.0 m) i ) × ((500 N) j ) = (1500 N•m) k
pointing out of the "page" with mag. 1500 N•m
The beam is held in place in a horizontal position, so the torques cancel and
(800 N) r = 1500 N•m
r = (1500 N•m)/(800 N) = 1.875 m ≈ 1.9 m

Answer:
d = 1.022 [m]
Explanation:
Work in physics is defined as the product of force by distance. In this way we have the following expression.
[tex]W=F*d[/tex]
where:
W = work done = 180 [J] (units of Joules)
F = force = 176 [N]
d = distance [m]

Why do clownfish rarely go far from their home
Answer:
In the wild, clownfish rarely leave their anemone home. In fact, part of its purpose is to defend the anemone from other fish. However, clownfish bred in aquariums (without an anemone home) may still have this instinct, but it’s much calmer than wild harvested species.
Explanation:
A piece of wood 400N in weight and 50cm X 30cm X 20cm in size lies on 50cm X 20cm face. Calculate the pressure exerted by it.
Answer:
4kPa
Explanation:
P = force/area
= 400/(0.5×0.2)
= 4000Pa(4kPa)
Answer:
4000pascal
Explanation:preassure = force/area
F = 400N
A = 50cmx 20cm = 1000 cm sq
so we have to convert the area in metre square
so when convert we get the answer 1/10 = 0.1m square
now as per the equation of preassure we have to divide 0.1/400
and then we get the answer 4000pascal.
