Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Which of the following is NOT a major factor in understanding climate?
a water
b clouds
c mountains
d altitude
Answer:
The Answer is CExplanation:
Bc its not part of a Question and you can know now The mountains is not right and climesand this much be the answer i dont know tho so this got to be Its ok now b yc. mountains is not a major factor in understanding climate.
Water is a major factor which can affect the climatic condition the high water content in the atmosphere is responsible for rain where as low or less content in atmosphere makes the climate hot and dry. Clouds when are dense cause rain and when there are few clouds and less denser then it is indicative of a hot day. Places situated on high altitude have cool climate as compared to the places located on plains.Mountains do not affect the climatic condition of a region. Instead the altitude with which the mountain is associated will help in understanding the climatic condition.Hence, c. mountain is the correct option.

Calculate the electrostatic force between a negatively charged PVC pipe (m = 300 g, q = -0.0000007 C) and a positively charged sweater (m = 650 g, q = 0.0000009 C) when they are held 6 cm apart (the centers of their charges are 6 cm apart). Your answer should include the magnitude of the force and clearly state whether they would be pushing or pulling each other with that amount force.
Answer:
1.575 N
Explanation:
Given that,
Charge on a PVC pipe, q₁ = -0.0000007 C
Charge on a positively charged sweater, q₂ = 0.0000009 C
Separation between charges, d = 6 cm = 0.06 m
We need to find the magnitude of the force between charges. The force between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}\\\\F=\dfrac{9\times 10^9\times 0.0000007 \times 0.0000009 }{(0.06)^2}\\\\F=1.575\ N[/tex]
So, the electrostatic force has a magnitude of 1.575 N.

How much force is used to lift a 42 kg object at a constant velocity? Why?
Answer:
equal to its weight which is 42x9.8
Explanation:
Mr. Linnartz climbs a vertical distance of 100 meters in 20 seconds. If his weight is 990 newtons what is the power he has exerted?
Answer:
4950W
Explanation:
Given parameters:
Height = 100m
Time = 20s
Weight = 990N
Unknown:
Power = ?
Solution:
Power is the rate at which work is done.
Power = [tex]\frac{Work done }{time }[/tex]
Workdone = Force x distance
Input the parameter and solve for the workdone;
Workdone = 990 x 100 = 99000J
Now;
Power = [tex]\frac{99000}{20}[/tex] = 4950W

A golfer drives her golf ball from the tee down the fairway in a high arcing shot. When the ball is at the highest point of its flight
a) the velocity and acceleration are both zero
b), The x-velocity is zero and thе y-velocity is zero
c) the x-velocity is non-zero, but the y-velocity is zero
d) thе velocity iѕ non- zero, but the acceleration is zero
Answer:
Correct Choice: c)
Explanation:
When an object is launched with an angle with respect to the horizontal, it describes a curved path exclusively under the action of gravity.
The velocity at any point of the path has two components:
The horizontal component has a constant value because no acceleration acts in that direction.
The vertical component has a variable value that depends on the acceleration of gravity and the time.
When the golfer drives the golf ball in a high arcing shot it reaches a maximum height and then returns to the ground.
a) The velocity is never zero until the ball hits the ground. The acceleration is never zero. False
b) The x-velocity is constant and equal to the horizontal component of the initial velocity. The y-velocity is zero at the highest point. Only one condition is true, thus the whole statement is False.
c) The x-velocity is never zero, and the y-velocity is zero as explained above. True
d) The velocity is non-zero, and the acceleration is not zero. False
Its velocity as well as acceleration are both non-zero.
This seems to be attributable to the reality that towards the maximum height, just the vertical dimension of that though velocity approaches zero. These same horizontal parts are already in play. As a result, the velocity would be non-zero.Gravity's acceleration would operate upon that ball, hence the acceleration will then be non-zero.As a result, the aforementioned response is correct.

Which factor can decrease the kinetic energy of an object?
Decrease in volume
Decrease in speed
Increase in temperature
Increase in speed
Previous
Answer:
*Decreasing an object's velocity can increase kinetic energy. *Increasing an object's velocity can decrease kinetic energy. *The velocity of an object has no effect on kinetic energy.
ExplanIf the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure (Figure 1).
What is Otter's average velocity over his entire trip when it takes him 2 minutes to walk 100 meters north and another 1 minute to walk 70 meters south?Express your answer using the proper SI units. Round your answer to two decimal places, and include a direction if necessary.
Answer:
0.50m/s
Explanation:
Average velocity is the change in displacement of a body with respect to time.
Velocity = ∆S/∆t
∆S = 100m - 70m
∆S = 30m
∆t = 2min - 1 min
∆t = 1min = 60secs
Substitute the given parameters into the formula for velocity
Velocity = 30m/60s
Velocity = 1/2 m/s
Average Velocity = 0.5m/s

calculate the area of the brick if the pressure is 180pa and the force 80N
Answer:
A = 0.44 [m^2]
Explanation:
To solve this problem we must remember that pressure is defined as the relationship between Force and area, so we have the following equation:
P = F/A
where:
P = pressure = 180 [pa]
F = force = 80 [N]
A = area [m^2]
Now replacing and solving:
180 = 80/A
A = 80/180
A = 0.44 [m^2]
