Answers
Answer: 75 N
Because we're finding the force, we need to use F = ma. M (Mass) = 25 and A (Acceleration) = 3. Multiply 25(3) to get 75. So, you're answer should be 75 N.

Answers
Globular star clusters form from tightly packed groups and/or older ancient stars.
What are globular star clusters?Globular star clusters can be defined as ancient stars packed in a spherical and/or symmetrical shape.
Globular star clusters represent the most common types of groups (i.e., clusters) of ancient stars.
These groups of stars (globular) are characterized to be densest in the center of the cluster.
In conclusion, globular star clusters form from tightly packed groups and/or older ancient stars.

A skydiver jumps from a stationary helicopter and reaches a steady vertical speed. She then opens her parachute. Which statement about the falling skydiver is correct?
A As her parachute opens, her acceleration is upwards.
B As she falls at a steady speed with her parachute open, her weight is zero.
C When she accelerates, the resultant force on her is zero.
alda
D When she falls at a steady speed, air resistance is zero.
Answers
Answer:
A) As her parachute opens, her acceleration is upwards.
Explanation:
The acceleration is the rate of change of the velocity.
Thus, if you have positive velocity and positive acceleration, your velocity increases
If you have positive velocity and negative acceleration, then your velocity decreases.
(The opposite happens when you have negative velocity).
Now, when the skydiver is falling, her velocity is downwards.
When she opens her parachute, her velocity downwards decreases.
This means that when she opens her parachute, she will have an acceleration in the opposite direction to her velocity, then at this point her acceleration is upwards.
We can conclude that the correct option is:
A) As her parachute opens, her acceleration is upwards.

What makes the results of a scientific experiment accurate? (5 points)
Answers
Answer:
A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.
Explanation:
Answer: when you repeat it and get the same results
Explanation:
When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

When the wave enters shallow water, its speed slows to 3.2 m/s. What is the wavelength of the wave in the shallow water?
Answers
Answer:
The wavelength of the wave in shallow water is 2.91 m.
Explanation:
Given;
frequency of the wave, f = 1.1 Hz
speed of the wave in deep water, v₁ = 5.7 m/s
speed of the wave in shallow water, v₂ = 3.2 m/s
The wavelength of the wave in the deep water is calculated as;
λ₁ = v₁/f
λ₁ = 5.7 / 1.1
λ₁ = 5.18 m
The wavelength of the wave in the shallow water is calculated as;
λ₂ = v₂/f
λ₂ = 3.2 / 1.1
λ₂ = 2.91 m
Therefore, the wavelength of the wave in shallow water is 2.91 m.

the angle of incidence is always equal to the angle of reflection,
Explanation:
Important Information. When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.

How do the nuclei of covalently bonded atoms help keep the bond together?
Neutral particles in the nucleus provide enough mass that the force of gravity holds the atoms together.
Neutral particles in the nucleus can become positive or negative in order to balance the charges.
Positive particles in the nucleus change into negative particles that enter electron shells.
Positive particles in the nucleus are attracted to shared electrons, so the atoms stay close together.

Three dogs scout sparky and dusty are playing with a teddy bear. Scout and sparky are pullung the teddy bear to the left
Answers
Answer:
To the left side.
Explanation:
The teddy bear will move towards the left side because more force is applied by scout and sparky than dusty. The reason for this movement of teddy bear to the left is due to more force is applied by the two dogs present at the left side of the teddy bear while on the other hand, one dog is present at the right side of teddy bear which applied less force so that's why we can say that the teddy bear moves to the left side rather than to the right side.
