According to this graph, the acceleration
is approximately:
Velocity (m/s)
1 2 3 4
Time t(s)
5
A. 4 m/s2
B. 2 m/s2
C. 1 m/s2
D. 3 m/s2
The acceleration is approximately 4 m/s². Therefore, the correct answer is:
A. 4 m/s²
To determine the acceleration from the graph, we need to look at how the velocity changes over time. Acceleration is defined as the rate of change of velocity with respect to time. In other words, it is the slope of the velocity-time graph.
Looking at the graph, we can see that the velocity changes from 0 m/s to 4 m/s over a time interval of 2 seconds. To calculate the acceleration, we use the formula:
Acceleration (a) = Change in velocity / Change in time
Acceleration (a) = (4 m/s - 0 m/s) / (2 s) = 4 m/s²
So, the acceleration is approximately 4 m/s². Therefore, the correct answer is:
A. 4 m/s²

Surveyors frequently use trig functions. Suppose that you measure the angle from your position to the top of a mountain to be 2.50∘. (Figure 6) If the mountain is 1.00 km higher in elevation than your position, how far away is the mountain?
Answer:
22.9km
Explanation:
If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain
What are trigonometric functions?A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.
As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,
By using the tangent trigonometric function for the right triangle
tanθ = height /distance
tan 2.5° = 1000 m /distance
distance =1000 m /tan 2.5°
=22903 m
=22.9 km
Thus, the mountain is 22.9 km far away from your position

In a trial, an expert witness uses the conservation of momentum to demonstrate which initial velocities would give the final states that occurred in the accident. Can using the conservation of momentum be justified in this case? Yes, because momentum is conserved in all collisions. No, momentum is only conserved in elastic collisions which this is not. No, energy is always conserved, but momentum is only sometimes conserved. Yes, because momentum is conserved in inelastic collisions which all car accidents are.

The pressure due to water at the bottom of the tank is 200000 Pascal.
What is pressure?It is the ratio between the force being applied and the surface area being applied to. The force delivered perpendicularly to an object's surface per unit area across which that force is dispersed is known as pressure.
Given parameters:
Depth of the tank = 25 meter.
Depth of water in the tank: d = 25×4/5 meter = 20 meter.
Density of water: ρ = 1000 kg/m³.
Acceleration due to gravity: g = 10 m/s².
Hence, the pressure due to water at the bottom of the tank
= depth of water (d) × density of water (ρ) × acceleration of the gravity (g)
= 20 meter × 1000 kg/m³ × 10 m/s²
= 200000 Newton/meter²
=200000 Pascal.
Hence, the pressure due to water at the bottom of the tank is 200000 Pascal.

A bullet is fired horizontally at 343 m/s from the top of a building where height is 37.3 m. The built will be
in flight for seconds
Answer:
Explanation:
A classic projectile motion question. Horizontal motion does not matter whatsoever in the context of this equation as we are looking at the vertical component of velocity only. Since the question states that it is fired horizontally, there is no vertical component of velocity. Thus, v0y = 0.
Assuming the projectile is on the Earth, we can use the free-fall acceleration, 9.8 m/s^2.
The question gives us Δy, which is 37.3m.
Using the second kinematics equation, Δy = v0t + (at^2)/2, we can substitute in the values.
37.3 = 0 + 0.5(9.8)t^2
37.3 = 4.9t^2
7.61224489796 = t^2
t = 2.75902970226 seconds.

It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.
Answer: It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.
Explanation:
When Skyler exerts a force of 52 N on the wagon and there is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N then Net force, mass and acceleration of the wagon will be 305.2 N, 31.02kg and 0.9 m/s² resp.
What is Force ?Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. when net force acting on body is zero then it is called as balanced force and net force on the body is non zero then it is called as unbalanced force. unbalanced force are responsible for the motion of the body.
in this problem, Skyler is applying 52 N force to a wagon, there is resistance of 24N of force. Combined Wight is 304 N is directed downwards. a vector diagram is shown in the figure which gives the Net force.
the resultant force between resistance and applied force
F = 52 - 24 = 28N... means total of 28N of actual force is applied on the wagon in x direction.
There is downward force as weight, hence magnitude of net force acting on the wagon is.
F²(net) = F₁²+F₂² + F₁F₂cosθ
θ = 90, cos 90 = 0
F²(net) = F₁²+F₂²
F²(net) = 28² + 304²
F²(net) = 93200
F (Net) = [tex]\sqrt{93200\\[/tex] = 305.2 N
To get mass and acceleration,
weight W = mg
304 = m*9.8
m = 31.02 kg mass of the wagon is 31.02kg
F = ma
28 = 31.02*a
a = 0.9 m/s²
Acceleration of the wagon is 0.9 m/s². this is forward acceleration.
Hence Net force, mass and acceleration of the wagon is 305.2 N, 31.02kg and 0.9 m/s² resp.

Imagine that Yusef had a diet with absolutely no fat. What impact would this have on his overall health?
OPTIONS:
A.
He would have absolutely no energy.
B.
He would more easily absorb nutrients.
C.
He would be unable to absorb vitamins.
D.
He would have a compromised immune system.
PLEASE NO LINKS
Answer:
A.
Explanation:
In addition to helping you lose weight by using calories on more filling foods, following a low-fat diet can help you ward off serious medical conditions, including heart disease, high cholesterol, and diabetes. The body needs some fat to function properly.
If Yusef had a diet with absolutely no fat then He would have absolutely no energy. Hence A is correct option.
What fat do to your body?Fat aids in the body's absorption of vitamins A, D, and E. These vitamins are only absorbed with the aid of lipids because they are fat-soluble. Body fat is created from any fat that is not utilized by the body's cells or transformed into energy.
According to research, the majority of fat cells in adipose tissue are produced by cells that line the blood vessels. This realization might inspire fresh methods for treating and preventing obesity. Our metabolism, reproduction, and life lengths are all regulated by white adiposity, or fat, tissue.
Hence option A is correct.
