As you climb a mountain, the boiling point (temperature) of water:
1. decreases
2. remains at 100° C
3. increases
Answer:
1, decrease
Explanation:
At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.
b) What is work? Write down the types of work.

Cindy runs 2 kilometers every morning. She takes 2 minutes for the first 250 meters, 4 minutes for the next 1,000 meters, 1 minute for the next 350 meters, and 3 minutes for the rest.
Cindy’s average speed for the entire run is meters per minute. One kilometer is the same as 1,000 meters.
Answer:
200 m/min.
Explanation:
From the question given, we obtained the following data:
Total distance = 2 km
Total time = 2 + 4 + 1 + 3
Total time = 10 mins
Average speed =.?
Next, we shall convert 2 km to metre (m). This can be obtained as follow:
1 km = 1000 m
Therefore,
2 km = 2 km × 1000 m / 1 km
2 km = 2000 m
Therefore, 2 km is equivalent to 2000 m.
Finally, we shall determine the average speed of Cindy as follow:
Total distance = 2000 m
Total time = 10 mins
Average speed =.?
Average speed = Total distance /total time
Average speed = 2000 /10
Average speed = 200 m/min.
Therefore, the average speed of Cindy is 200 m/min.

What is the sum of all forces that act upon an object called?
a
Net force
b
Balanced force
c
Unbalanced force
d
Gravitational force
Answer:
net force
Explanation:
The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

- Approximately what are the coordinates of the Hawaii Hot
Spot?
(1) 50 N, 120 W
(3) 25 N, 158 W
(2) 25 N, 158 €
(4) 25 S, 158 E
Answer: (3) 25°N, 158°W
Explanation:
The Hawaii Hotspot is one of the most popular on the planet and is the reason the Hawaii islands were created as it created volcanoes under the Hawaii islands that erupted as the Pacific plate moved over them and then the lava cooled thereby forming the different Hawaii islands.
The approximate location of the hotspot is 25°N, 158°W in the pacific ocean.

This is what your experiment was intended to demonstrate or investigate. "As temperature rises, honey's viscosity falls."
What is an experiment?The experiment appears to investigate the relationship between honey viscosity and temperature, and after reading the question.
You must look at your experimental results here; it's likely that you discovered that viscosity does indeed drop as the temperature rises.
The final task at hand is to list the challenges and issues you encountered throughout the experiment and make suggestions for how to address them in order to conduct future experiments that are more successful.
Therefore, the temperature has a considerable influence on viscosity, however, the particular substance also affects this relationship.

Suppose you were designing an elevator. How could you use the concept of an Atwood machine to minimize the force required to move the elevator up and down? If possible, discuss your answer with your classmates and teacher.
Answer:
an elevator we can use a counterweight that has the same mass as the empty box,
Explanation:
An Atwood machine consists of two masses connected by a rope through a pulley, in this case the acceleration of the system is proportional to the difference in masses, in the case of equal masses the acceleration is zero.
In the design of an elevator we can use a counterweight that has the same mass as the empty box, in that case when there are no people in the elevator, the natural acceleration is zero and there is no need to apply any force and therefore no power is needed. the motor.
When you have people inside, the power of the motor is what you need to lift the people, not the box, this reduces the power needed by the elevator motor by a high factor.
Using Atwood machine concept, we can state that the elevator can use a system of counterweights that balance the weight inside the box and minimize the force required to move the elevator up and down.
We can arrive at this answer because:
An Atwood machine consists of a system of two masses that counterbalance each other.In this system, the acceleration is caused by the difference between these masses, if there are no differences between them, there is no acceleration of the system.In the case of the elevator, a counterweight system would provide a balance when there were people inside the box.This is because the counterweight would have the mass equal to the mass of the empty box and this would make the entire system not have acceleration.However, when people enter the box, there would be a difference in mass and the system would have acceleration, without forcing a greater force to do so, but using engine power.With that, we can say that an elevator can act as an Atwood machine.

A car weighs 2,000 kg. It moves along a road by applying a force on the road with a parallel component of 560 N. There are two passengers in the car, each weighing 55 kg. If the magnitude of the force of friction experienced by the car is 45 N, what is the acceleration of the car?
Answer:
The acceleration of the car is 4.10 m/s².
Explanation:
The acceleration of the car can be found using the following equation:
[tex] F = ma [/tex] (1)
Where:
F is the force
m is the mass
a is the acceleration
The force is:
[tex]F = F_{p} - F_{f}[/tex] (2)
Where:
F(p) is the parallel force = 560 N
F(f) is the force of friction = 45 N
By entering equation (2) into (1) we have:
[tex]F_{p} - F_{f} = (m_{c} + m_{p}*2)a[/tex]
[tex] 560 N - 45 N = (2000 kg + 55*2 kg)a [/tex]
[tex] a = \frac{2000 kg + 55*2 kg}{515 N} = 4.10 m/s^{2} [/tex]
Therefore, the acceleration of the car is 4.10 m/s².

15% input work is lost due to friction then what is the efficiency of machine?
Answer:
I think 50%
Explanation:
Because the efficiency of a machine is always less than 100%. And efficiency of a machine is 75%.
So, if 15% input work is lost due to friction then efficiency is maybe 50%.
