What is the net force required to accelerate a 5.3 kg box at a rate of 4.2 m/s^2?
Answer:
The answer is 22.26 NExplanation:
The force acting on an object given the mass and acceleration we use the formula
force = mass × accelerationFrom the question
mass = 5.3 kg
acceleration = 4.2 m/s²
We have
force = 5.3 × 4.2

When a ball is sitting still on top of a table, are the forces acting upon it balanced or unbalanced?
Answer:
Balanced
Explanation:
If a stationary object is staying still (in this case it's the ball) all of the forces acting upon it are balanced. If an object moving has balanced forces, it would move in the same direction at the same speed until a different outside force interrupts the equilibrium.
Hope this helps :)
This question involves the concepts of Newton's Second Law and Balanced Force.
The forces acting upon the ball are "Balanced".
Newton's Second LawAccording to Newton's Second Law whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of the force itself. This acceleration is directly proportional to the magnitude of the force and inversely proportional to the mass of the object.
Since, the ball is at rest and not moving. Hence, it has no acceleration and no unbalanced force is applied on it. The weight of the ball is balanced by the normal reaction provided by the table. Therefore, the forces acting on the ball are Balanced Forces.

What do x-direction and y-direction refer to when discussing an object's motion
Answer:
The x-direction and y-direction refer are used to refer to the location of an object as well as to the components of the motion of the object in a two dimensional space
Explanation:
In physics, in the analysis of the motion of an object in two dimensional space, the relative location of the object is specified using the measured distances in the x-direction from the y-axes and y-direction from the x-axes
In order to accurately specify the motion of the object, information regarding the component of the motion of the object in the x-direction and the component in the y-direction are required

One frequent sign of gender inequality in the United States is that women do not ___________. A. enjoy the same voting rights as men B. earn as much as men in similar occupations C. receive admission to college as much as men D. have equal power in most relationships
One frequent sign of gender inequality in the United States is that women do not earn as much as men in similar occupation. So, option (B) is correct.
What is gender inequality?Men and women are not treated equally in society, which social problem is referred to as gender inequality. Distinctions in genetics, psychology, or prevailing cultural norms in the society may be the cause of the treatment. While some of these distinctions are based on scientific research, others seem to be social constructs.
Numerous areas of study, such as education, life expectancy, personality, interests, family life, careers, and political affiliation, demonstrate the differences in gender experiences. Gender inequality impacts non-binary people and is experienced differently across cultural boundaries.

A person throws a ball horizontally from the top of a building that is 26.1 m above the ground level The ball lands 112 m away from the base of the building Neglect air resistance and useg = 9.81 m/s ^ 2
Answer:
v = 5.21 m/s
Explanation:
Let the initial speed be v.
The top of a building is 26.1 m above the ground level and the ball lands 112 m away from the base of the building.
We need to find the initial velocity of the ball.
Let it was at rest initially. Using the second equation of motion to find time of flight.
[tex]d=ut+\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2d}{g}} \\\\t=\sqrt{\dfrac{2\times 26.1}{9.81}} \\\\t=2.3\ s[/tex]
No, using the formula of speed.
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{12\ m}{2.3\ s}\\\\v=5.21\ m/s[/tex]
So, the initial velocity of the ball is 5.21 m/s.
In february a little town received snow on a daily basis. The first day they had 10 inches, 3 inches the second, 7 inches the 3rd, and 4 inches on the fourth day. What was the average snowfall?
Answer:
The average is 6
Explanation:
To find the average, you have to first add all the numbers. After you add all the numbers up, then you divide by how many numbers there are. This one had 4 numbers so you divide by 4
The average snowfall of the four days was 6 inches.
What is snow?
When atmospheric water vapor freeze into small ice crystals and falling in small white flakes or lying on the ground as a white layer, it is called snow.
In the question it is said that,
Amount of snow received by the town on first day = 10 inches.
Amount of snow received by the town on second day = 3 inches.
Amount of snow received by the town on third day = 7 inches.
Amount of snow received by the town on fourth day = 4 inches.
Total amount of snow received by the town on these four days = ( 10 + 3+ 7 + 4) inches.
=24 inches.
Hence, average amount of snow received by the town on these four days = total amount of snow received ÷ 4
= ( 24 ÷ 4) inches.
= 6 inches.
Hence, the average snow received by the little town was 6 inches on those days.

Which has more momentum? A 60 kg object traveling at 3 m/s or a 9 kg object traveling at 23 m/s.
Answer:
If we compare 270 J and 2 380.5 J the higher is 2 380.5 J which is A 9 kg object traveling at 23 m/s
Explanation:
A 60 kg object traveling at 3 m/s
Given:
m = 60 kg
v = 3 m/s
Unknown:
KE or kinetic energy
Formula and solution:
KE = 1/2 mv²
KE = 1/2 (60kg) (3m/s)²
KE = (30kg) (9m²/s²)
Final Answer:
KE = 270 kg·m²/s² or simplify as 270 J
A 9 kg object traveling at 23 m/s
Given:
m = 9kg
v = 23m/s
Unknown:
KE or kinetic energy
Formula and solution:
KE = 1/2 mv²
KE = 1/2 (9kg) (23m/s)²
KE = (4.5kg) (529m²/s²)
Final Answer:
KE = 2 380.5 kg·m²/s² or simplify as 2 380.5 J
You are designing an apparatus to shoot a water balloon through a 3rd story window (25m above the ground)
Answer:
The balloon needs a vertical velocity of approximately 22.14 m/s to reach the window
Explanation:
The given parameters are;
The destination of the designed water balloon we shoot = The 3rd story window
The height of the 3rd story window which the water balloon should reach = 25 m
Therefore, we have, the equation of motion of the water balloon given as follows;
v² = u² - 2 × g × s
Where;
[tex]u_y[/tex] = The initial vertical velocity of the balloon
[tex]v_y[/tex] = The final vertical velocity of the balloon = 0 m/s
g = The acceleration due to gravity = 9.8 m/s
s = The height the balloon is intended reach at the final velocity becomes 0 m/s = The height of the 3rd story window
∴ s = 25 m
Substituting the values, we have;
0² = [tex]u_y[/tex]² - 2 × 9.8 × 25
[tex]u_y[/tex]² = 2 × 9.8 × 25 = 490
[tex]u_y[/tex] = √490 = 7·√10
The initial vertical velocity of the balloon = [tex]u_y[/tex] = 7·√10 m/s
Therefore, the balloon needs a vertical velocity of 7·√10 m/s which is approximately 22.14 m/s to reach the window.
