Your training partner has stopped pedaling during the spinning class you are both taking. She wants to check her exercise intensity level. You have a piece of exercise technology for this job and can continue to pedal while keeping tabs on your workout progress. Select the choice below that you would be using.
Group of answer choices
Heart rate monitor
Blood pressure monitor
Stopwatch
Pedometer
Answer:
Heart rate monitor I think
Explanation:
you would know how intense the pedaling is by knowing your heart beat rate as of the pedaling is so intense your heart beat increases and if it was not so much your pedaling is not so intense.
This works also for any other sports .
~--Hope this helped--~
Answer: it’s Heart rate monitor
Explanation:
you use a heart rate monitor to check your intensity level by seeing how fast your heart goes
is space expanding within clusters of galaxies? why or why not?
No, since their gravity is powerful enough to keep them together even while the universe expands as a whole. Space is not expanding within clusters of galaxies.
What is a galaxy?A galaxy is a massive clump of gas, dust, and billions of stars and their solar systems bound together by gravity.
No, since their gravity is powerful enough to keep them together even while the universe expands as an entire.
Hence,space is not expanding within clusters of galaxies.

Which order is the brightest?
n = 0
n = 1
n = 2
The order of band in which the light becomes the brightest is n = 0.
What is diffraction?
Diffraction is the phenomena of the spreading of waves around obstacles. Diffraction occurs in electromagnetic radiation, such as light, X-rays, and gamma rays, etc.
When light waves pass near a barrier they tend to bend around that barrier and become spread out.
The order bands n=2 becomes dimmest due to the spreading out of the light wave.
Thus, the order of band in which the light becomes the brightest is n = 0.

A student made the claim that a 4 gram paintball fired from a paintball gun at 90 m/s could have about the same kinetic energy as a 1 gram BB pellet fired from a BB gun at 180 m/s.
Do you agree or disagree with the student's claim? Use evidence and mathematical reasoning to support your response.
This question involves the concept of kinetic energy.
The student's claim is "right".
Kinetic EnergyThe energy possessed by a body, by the virtue of its motion is called kinetic energy. Mathematically it is given by the following formula:
[tex]K.E =\frac{1}{2}mv^2[/tex]
where,
K.E = Kinetic energy m = massv = velocityTherefore,
For the paintball:
[tex]K.E = \frac{1}{2}(4\ g)(90\ m/s)^2[/tex]
K.E = 16200 J
For the pellet:
[tex]K.E = \frac{1}{2}(1\ g)(180\ m/s)^2[/tex]
K.E = 16200 J
Hence, both paintball and pellet will have same kinetic energy. The student is right.

Frictional force is reduced in smooth surfaces but is large in rough surfaces.
What is Force?Force is defined as an agent which causes a change in the motion or state of an object.
Forces are of two types:
Contact forces and Non-contact forcesContact forces include frictional force.
Frictional forces refers to the force which acts between two surfaces in contact by opposing the relative motion of one over the other
Frictional force depends on the nature of surfaces in contact where rough surfaces produce greater frictional force than smooth surfaces.
Therefore, frictional force is reduced in smooth surfaces but is large in rough surfaces.

A hot air balloon pilot is choosing a day and time to launch her new balloon. Table 1 shows the weather forecast for the next three days.
Temperature at 6 a.m. (°C). Temperature at 12 p.m. (°C). Temperature at 6 p.m. (°C)
Monday. 4. 18. 22
Tuesday. 6. 19. 24
Wednesday. 10. 20. 25
If the pilot wants to rise as high as possible while using as little fuel as possible, on which day should she launch her balloon? Explain your answer.
The balloon will rise the most on Wednesday due to high temperature that will increase the thermal energy of the balloon and cause it to rise higher.
Average daily temperatureThe average daily temperature of the different days is calculated as follows;
Monday = (4 + 18 + 22)/3 = 14.67 ⁰C
Tuesday = (6 + 19 + 24)/3 = 16.3 ⁰C
Wednesday = (10 + 20 + 25)/3 = 18.3 ⁰C
The average daily temperature of Wednesday is the greatest.

Romeo and Juliet are sitting on a balcony 1.2 meters apart. If Romeo has
a mass of 69.3 kg and Juliet has a mass of 52.0 kg, what is the attractive
force between them?
F = G M.m/r²
F = force, N
G = gravitational constant, 6.67 x 10⁻¹¹ Nm²/kg²
m,M = mass of object, kg
r = distance, m
F = 6.67 x 10⁻¹¹ x 69.3 x 52/1.2²
F = 1.669 x 10⁻⁷
We can expect the force of friction to be greater for an object moving on a surface if the surfaces in contact are
a) smooth and the object is heavier
b) smooth and the object is lighter
c) rough and the object is heavier
d) rough and the object is lighter
Answer:
c
Explanation:
Friction is caused by how rough and object is, and how much the object weighs, as this causes it to drag more.
