What would be the acceleration of an object with a mass of 5,000 g when hit with a force of 55 N?
Answer:
11 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass in kg
From the question
5000 g = 5 kg
We have
[tex]a = \frac{55}{5} \\ [/tex]
We have the final answer as
11 m/s²Hope this helps you

A cannonball with a perfect horizontal velocity of 80.0 m/s flies 320 m before hitting the ground. How much time was the cannonball in the air?
Time taken to reach height is 4 seconds.
Given that;
Velocity of cannon ball = 80 m/s
Height taken = 320 meter
Find:
Time taken to reach height
Computation:
S = ut + (1/2)gt²
320 = (80)(t) + (1/2)(10)(t²)
320 = 80t + 5t²
t² + 16t + 64
So,
t = 4
Time taken = 4 seconds

If a bicycle has an average acceleration of -0.44 m/s^2, and its initial forward velocity is 8.2 m/s, how long will it take the cyclist to bring the bicycle to a complete stop
Answer:
The value is [tex]t = 18.6 s[/tex]
Explanation:
From the question we are told that
The average acceleration of the bicycle is [tex]v = -0.44 \ m/s^2[/tex]
The initial forward velocity is [tex]u = 8.2 \ m/s[/tex]
Generally from kinematic equations we have that
[tex]v = u + at[/tex]
Here v is the final velocity of the bicycle and the value is v = 0 m/s
So
[tex]0 = 8.2 + (-0.44)t[/tex]
=> t = 18.6 s

Calculate the centripetal force of a ball on a string in circular motion if the mass is 7 kg
traveling at 3 m/s and the radius of the string is 4 meters.
0 11 N
0 14 N
0 16 N
0 25 N
Answer:
F = 16 N
Explanation:
Given that,
Mass of the ball, m = 7 kg
Speed of the ball in circular motion, v = 3 m/s
The radius of the string, r = 4 m
We need to find the centripetal force of a ball on a string in circular motion. The formula for the centripetal force is given by :
[tex]F=\dfrac{mv^2}{r}[/tex]
Putting all the values in the above formula
[tex]F=\dfrac{7\times (3)^2}{4}\\\\=15.75\ N[/tex]
or
F = 16 N
Hence, the correct option is (c).
Water
Wood
Neon gas
Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood
Answer:
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.
Answer:
A) wood, water, neon gas
Explanation:
wood, water, neon gas.
The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.

m/s? What is the change of position of the tank? What is its average velocity?
Given
Equation
Find
Diagram
12.00 min = 0.2 hr
8.00 min = 0.15 hr
Total distance:
(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) + (20.0 km/hr) (0.2 hr)
= 8.25 km
Average speed:
(10.0 km/hr + 15.0 km/hr + 20.0 km/hr) / 3
= 15 km/hr
Change in position:
(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) - (20.0 km/hr) (0.2 hr)
= 0.25 km
Average velocity:
(10.0 km/hr + 15.0 km/hr - 20.0 km/hr) / 3
≈ 1.67 m/s

Safety belts protect people in cars in the event of an accident because, according to Newton’s laws of motion, when an impact causes the car to suddenly change its motion -
A.the speed of the people always increases, since now they have not one but two forces acting on them.
B.the speed of the car always increases, giving it greater force since the mass will remain the same.
C.the car now has a greater overall mass - its own mass plus the mass of the object by which it has been struck.
D.the people in the car will continue to move in the same direction and at the same speed as before the impact.
Answer:
D :)
Explanation:
When an impact causes the car to suddenly change its motion, (D) the people in the car will continue to move in the same direction and at the same speed as before the impact.
What is Newton's first law of motion?
Newton's first law of motion states that Unless influenced by an imbalanced force, a body at rest stays at rest, and a body in motion keeps moving in a straight path at a constant pace. This law is commonly known as law of inertia and the resistance of a body to maintain its state of rest is called inertia of rest, same as, the resistance of a body to maintain its state of motion is called inertia of motion.
When a car is moving with certain speed, the car along with the people inside the car is in inertia of motion. In an event of accident, the car comes in rest in no time but the man in the car is still in inertia of motion. So, his body moves forward in the car which may cause injuries. To prevent such injuries, the people inside a car are advised to use safety belts.
So, correct answer is option (D).

How do animals affect the amount of carbon earth’s atmosphere
Answer:
Animals cerate Carbon Dioxide through the process of respiration.
All animals exhale carbon dioxide out through respiration and increase the level of carbon dioxide in the atmosphere and this is intaken by the plants for photosynthesis.
What is carbon cycle ?Carbon cycle is the geological process that balance the amount of carbon dioxide in the atmosphere and biosphere. Carbon dioxide is an essential gas that maintains the living condition on earth.
All animals inhales oxygen and exhales carbon dioxide out. This carbon dioxide is used by plants to carry photosynthesis in plants. Plants absorb this carbon dioxide and combine with water forming oxygen gas and glucose.
This process repeats cyclically and the level of oxygen and carbon in the atmosphere gets balanced. Therefore, animals have a significant role in carbon dioxide cycle and oxygen cycle.

Manu took a pebble and a sheet of paper both weigh one gram. His friend told that if we drop both at the same time, the pebble will fall straight to the floor, while the paper will slowly drift to the ground. Do you think friction have any role in this case? How can we relate that to the topic which we are learning today?
Answer: friction has no role to play in this case. because friction usually occurs between to parts which come in contacts. examples (a)our joints in the human body (b)two mechanical parts (shafts).
Explanation:
However what this topic relates to is gravity. The pebble and paper both weigh one gram, but have different density this is the sole reason why if both are drop from same height the pebble would reach the ground faster than the paper because it is more denser. unlike the paper with a lesser density which would take a longer time to reach the ground.

Which best compares concave and plane mirrors?
Plane mirrors produce only virtual images, and concave mirr
Plane mirrors produce only real images, and concave mirror
Concave mirrors produce only real images, and convex mirro
Answer:
Explanation:
Hi! It would be A. Plane mirrors produce only virtual images,and concave mirrors produce real and virtual images.
Plane mirrors construct only virtual images, and concave mirrors make real and virtual images. Thus, this statement best corresponds concave and plane mirrors.
What are virtual images?A virtual image exists represented as the opposite of a real image, thus an image that cannot be obtained on a screen stands produced as a virtual image. The motivation for this exists in the fact that the beams of light that form a virtual image never connect therefore a virtual picture can never be projected onto a screen. Examples: Image formed in a plane mirror, an image constructed on the front and back surfaces of a spoon, etc.
Therefore, the (A) option exists as the accurate answer.
