Calculating net force
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0
What type of force causes the motion of an object to change
Answer:
Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.
Explanation:
Answer:
Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces.

14. Saeed is pulling a 6 kg heavy rock with an upward force of 40 N but does not succeed to lift it up. What is the magnitude of the normal force on the rock?
Answer:
58.8 N
Explanation:
The normal force is calculated as equal to the perpendicular component of the gravitational force.
Thus; N = mg
We are given m = 6 kg
Thus;
N = 6 × 9.8
N = 58.8 N
Thus, magnitude of normal force on the rock = 58.8 N

What differentiates one layer of the atmosphere from one another?
Please help
Answer: The stratosphere and the troposphere are defined by the variation in temperature with height. Within a troposphere, the temperature drops as altitude increases, and drops fast enough for convection to occur. Whereas within a stratosphere, the temperature rises with increasing altitude. Features of the atmosphere change with altitude: density decreases, air pressure decreases, temperature changes vary. Different temperature gradients create different layers within the atmosphere. The lowest layer is the troposphere where most of the atmospheric gases and all of the planet's weather are located.

Which location, 23 degrees or 48 degrees would experience the same earthquake at stronger intensity?Explain why.
Answer:
48 degress
Explanation:
An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.
Explain why a charged body loses its charge if we touch it with our hand?

A 96 kg man is standing in an elevator. The man experiences a net force when the elevator moves at an acceleration of 4.0 m/s2 upward and downward. Find both net forces
Answer:
The net upward force the man experiences is approximately 1,324.8 N
The net downward force the man experienced is approximately 556.8 N
Explanation:
The given mass of the man, m = 96 kg
The acceleration of the elevator, a = 4.0 m/s²
According to Newton's third law of motion which states that action ad reaction are equal and opposite, when the elevator moves upwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The force of the elevator pushing upwards, m·a
∴ ↑F = m·g + m·a
Where;
F = The net force the man experiences
m = The mass of the man = 96 kg
g = The acceleration due to gravity ≈ 9.8 m/s²
a = The acceleration of the elevator = 4 m/s²
∴ ↑F = 96 kg × 9.8 m/s² + 96 kg × 4 m/s² ≈ 1,324.8 N
The net upward force the man experiences ≈ 1,324.8 N
When the elevator moves downwards, we have;
The net force the man experiences, F = Gravitational force, m·g + The loss of the gravitational force as the floor moves further downwards, -(m·a)
∴ F = m·g + -(m·a) = m·g - m·a
F = m·g - m·a
∴ ↓F = 96 kg × 9.8 m/s² - 96 k × 4 m/s² ≈ 556.8 N
The net downward force the man experienced ≈ 556.8 N
If a ball that is 10 meters above the ground is thrown horizontally at 5.51 meters per second. a. how long will it take for the ball to hit the ground? b. how far will the ball travel in the horizontal direction before it hits the ground?
Answer:
a. t = 1.43 s
b. d = 7.88 m
Explanation:
a. The time of flight can be found using the following equation:
[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = -10 m
[tex]y_{0}[/tex]: is the initial height = 0
[tex]v_{0_{y}}[/tex]: is the initial speed in the vertical direction = 0
g: is the acceleration due to gravity = 9.81 m/s²
By solving the above equation for "t" we have:
[tex] t = \sqrt{\frac{2y_{f}}{g}} = \sqrt{\frac{2*10 m}{9.81 m/s^{2}}} = 1.43 s [/tex]
Hence, the ball will hit the ground in 1.43 s.
b. The distance in the horizontal direction can be found as follows:
[tex] x_{f} = x_{0} + v_{0}t + \frac{1}{2}at^{2} [/tex]
Where:
x₀: is the initial position in the horizontal direction = 0
a: is the acceleration in the horizontal direction = 0 (it is moving at constant speed)
[tex] x_{f} = 5.51 m/s*1.43 s = 7.88 m [/tex]
Therefore, the ball will travel 7.88 m before it hits the ground.

compresses a maximum acceleration of 15 m/s?.
a) Determine the spring constant.
b) Determine the mass.
d) What is the velocity when the mass reaches maximum acceleration?
c) Deterinine the net force when the mass passes 0.10m compression
d) Determine the acceleration when the mass passes 0.10m compression.
e) Determine the velocity when the mass passes 0.10m compression
Answer:
I started answering this before everything was erases, but briefly
W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150
Also F = - K X = 150 * 1/5 = 30 N at max extension
m = F / a = 30 /15 = 2 kg
Since max extension occurs at t = 0 you can write
x = A sin ω t
v = ω A cos ω t
a = -ω^2 A sin ω t note that there is no phase angle here
Also at .1 compression
.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6
Substiture these values above to get velocity and acceleration when
ω t = 30 deg

If the frequency of a wave is 0.25 Hz, what is its period?
A) 0.25 s
B) 2 s
C) 4 s
D) 4 HZ
Answer:
C
Explanation:
frequency = 1 / period
so
frequency = 0.25
0.25 = 1 / period
1 / 0.25 = period
4 s = period
it is not 4 Hz because period is the time taken
so the answer is C
