What's the answer to this question?​

Answers

Answer:

The barometer is supporting 75 cm of Hg due to atmospheric pressure.

Since the manometer is open to air pressure, the gas pressure is supporting the air pressure plus the 30 cm of Hg.

So the "absolute" gas pressure is 75 + 30 = 105 cm of Hg.

A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?

Answers

Acceleration = (force) / (mass)

Acceleration = (6.81 x 10⁻³ N) / (252 kg)

Acceleration = 2.70 x 10⁻⁵ m/s²

Time = (change in v) / (acceleration)

Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)

Time = 9,703,704 seconds

That's  2,695.5 hours , or  112.3 mean solar Earth days .

1. A gas has a volume of 300 mL at 40 kPa of pressure. What will its volume be if the pressure is changed
to 80 kPa?
How to work it out?

Answers

Answer:

V₂ = 150 mL

Explanation:

Given that,

Initial volume of a gas, [tex]V_1=300\ mL[/tex]

Initial pressure, [tex]P_1=40\ kPa[/tex]

We need to find the volume of gas if the pressure is changed to 80 kPa. Boyle's law states that the relationship between pressure and volume is inverse. Mathematically,

[tex]P_1V_1=P_2V_2[/tex]

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{300\times 40}{80}\\\\V_2=150\ mL[/tex]

So, the new volume is 150 mL.

A rope is used to pull a 4.0 kg bucket of water upwards out of a deep well with an applied force 45 N. If starting from rest, what speed will the bucket have after experiencing this force for 2 seconds?

Answers

Answer:

v = 22.5 m/s

Explanation:

The speed of the bucket can be found using the following equation:

[tex] V_{f} = V_{0} + at [/tex]

Where:

[tex]V_{f}[/tex]: is the final speed =?

[tex]V_{0}[/tex]: is the initial speed = 0 (starts from rest)

a: is the acceleration

t: is the time = 2 s

We need to find the acceleration, it can be found as follows:

[tex] F = ma [/tex]

Where:

F: is the force = 45 N

m: is the mass = 4.0 kg

[tex] a = \frac{F}{m} = \frac{45 N}{4.0 kg} = 11.25 m/s^{2} [/tex]

Now, the speed is:

[tex] V_{f} = V_{0} + at = 11.25 m/s^{2}*2 s = 22.5 m/s [/tex]

Therefore, the speed that the bucket will have is 22.5 m/s.

The limitation of using cellulose is its lack of mass production.

Cellulose is a polymer of glucose. It is obtained from glucose by condensation polymerization to yield a long chain.

Cellulose materials have a high potential of being quite useful as important materials for diverse applications.

However, the problem with cellulose materials is that they can not really be mass produced. This limitation has long encumbered the possibility of using cellulose materials for various applications in material science.

This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

What is the magnitude of the force that Earth exerts on the bag?

Answer:

47.3 N

Explanation:

the entire system shown in the question above is at rest. Which greatly facilitates the calculation that we must do. In this case, to measure the magnitude that the force of the earth has on the backpack, you only need to add the two forces that you already know in the system.

In that case, it would be, you should calculate:

They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.

A hotwheels car is rolled from 0.72 meters to the 1.51 meter mark. What is the displacement of the toy car?
(do not enter units into your answer in canvas)

Answers

Answer:

it is d]

Explanation:

The displacement of the toy car will be 0.79 meters.

What is displacement?

The shortest route between two points is displacement.

It is a vector quantity to be displaced. This suggests that it has a size and a direction, and that it may be thought of as an arrow pointing from one place to another.

Distance is never less than displacement; it must always be more than or equal to it.

Displacement can be zero if the starting and end point are the same.

According to the question, the Hot wheel car rolled from 0.72 meters to the 1.51-meter mark.

So, the displacement of the toy car will be :

⇒1.51-0.72

=0.79

Hence, the total displacement will be  0.79 meters.

A giraffe, standing 6.00 m tall, bites a branch off a tree to chew on the leaves
and lets the branch fall to the ground. How long does it take the branch to hit
the ground?

Answers

Answer:

1.11 s.

Explanation:

From the question given above, the following data were obtained:

Height (H) = 6 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =.?

The time taken for the branch to hit the ground can be obtained as follow:

H = ½gt²

6 = ½ × 9.8 × t²

6 = 4.9 × t²

Divide both side by 4.9

t² = 6/4.9

Take the square root of both side

t = √(6/4.9)

t = 1.11 s

Therefore, it will take 1.11 s for the branch to hit the ground.
