What net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2?
Answers
The net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2 will be F = 18.4375 N
What is Newton's second law of motion ?Newton's second law of motion states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
For a constant mass , force is equal to Force = mass * acceleration
given
mass(M) = 2.95 kg
acceleration(a) = 6.25 m/s^2
Force(F) = ?
Force(F) = mass(M) * acceleration(a) (from Newton's second law of motion )
F = 2.95 * 6.25
F = 18.4375 N
The net force would be needed to accelerate a 2.95kg bowling ball at 6.25m/s^2 will be F = 18.4375 N

Using the velocity versus time graph, what was the average acceleration of the object during segment B?
a) 0 m/s/s
b)20 ms/s
c) 10 m/s/s
d) 5 m/s/s
Answers
Answer:
the answer is B 20 ms/s
Explanation:
N/A
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.
Average acceleration- Acceleration is defined as the rate of change of acceleration. Average acceleration for an interval can be defined as the rate of change of velocity for that interval per time.
Let [tex]\Delta v[/tex] be the change in velocity and [tex]\Delta t[/tex] be the change in time in a given time interval. Then average acceleration is,
[tex]a= \dfrac{\Delta v}{\Delta t}[/tex]
At segment B, It starts at 4.5 seconds and ends at 10 seconds. The total time interval for this segment is 5.5 seconds.Therefore,
[tex]\Delta t=5.5[/tex]
Now the change in velocity for segment B. In segment B the velocity does not change at any point and keeps the value of 20 m/sec at the time interval.
According to the definition of the average acceleration when an object is changing its velocity (whether by a constant amount or a varying amount) then it is an accelerating object. And an object with a constant velocity is not accelerating.
Thus the for the given velocity versus time graph the average acceleration of the object during segment B is 0 m/s/s.Hence, option A is the correct option.

predict the long term cost and benefit of using renewable or non renewable resources. please help will give brainliest
Answers
Answer:
The long term cost and benefit of renewable resources is that it is most likely a one-time purchase kind of thing. For example, if you use solar energy, you only have to buy the solar panels for your roof once. However, if you use gas oil to cook, you have to keep buying since it runs out. Sunlight doesn't run out.
The long term cost and benefit of non renewable resources is that it is something you can profit off of very easily. It will take a lot of time for people to completely switch over to renewable resources, so it is something that can steadily bring in money. Examples of non renewable resources that people constantly use is oil, gas, coal, etc.

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?
Answers
Answer:
1.17427...kg
Explanation:
Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.
p=mv, where p is momentum, m is mass, and v is velocity
28.3=24.1(m)
divide both sides by 24.1
you get 1.174273859
Answer:
[tex]\boxed {\tt 1.17427386 \ kilograms}[/tex]
Explanation:
The formula for momentum is:
[tex]p=mv[/tex]
From this formula, we know that mass can be found by dividing the momentum by the velocity.
[tex]\frac{p}{v}=m[/tex]
The momentum is 28.3 kg m/s and the velocity is 24.1 m/s
[tex]p=28.3 \ kg \ m/s \\v=24.1 \ m/s[/tex]
[tex]\frac{28.3 \ kg \ m/s }{24.1 \ m/s} =m[/tex]
Divide. The meters per second or "m/s" will cancel each other out.
[tex]\frac{28.3 \ kg}{24.1} =m[/tex]
[tex]1.17427386 \ kg=m[/tex]
The mass of the object is 1.17427386 kilograms.

what do you mean by electric wind?
Answers
Explanation:
The electric field is normal to any conductor charged surface, then any negatively charged sharp end will concentrate the electrons in order to achieve that (being rejected by the others on main body), that also implies a huge voltage drop nearby the edge, meaning high electric field in the direction aimed by the sharp end, that field becomes strong enough (when charged by electrostatic machines) to propel electrons out causing air movement in that direction (a flame will bend because of that wind).
Ion wind, ionic wind, coronal wind or electric wind is the airflow induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative to ground. Ion wind is an electrohydrodynamic phenomenon

A 2.0 Kg box is being pulled up a ramp with a force of 25.0 Newtons. The ramp has an incline of 30 degrees. If the coefficient of friction is 0.752, find the acceleration of the block up the ramp. You may round your answer to the nearest tenth where necessary!!!
Answers
Answer:
The acceleration of the block is 1.21 m/s².
Explanation:
Given that,
Mass = 2.0 kg
Force = 25.0 n
Angle = 30°
Coefficient of friction = 0.752
We need to calculate the acceleration of the block
Using balance equation
[tex]F-(mg\sin\theta+\mu mg\cos\theta)=ma[/tex]
Put the value into the formula
[tex]25-(2.0\times9.8\sin30+0.752\times2.0\times9.8\cos30)=2.0a[/tex]
[tex]a=\dfrac{25-(2.0\times9.8\sin30+0.752\times2.0\times9.8\cos30)}{2.0}[/tex]
[tex]a=1.21\ m/s^{2}[/tex]
Hence, The acceleration of the block is 1.21 m/s².
