Answer:
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
Explanation:
Total force required = Mass x Acceleration,
F = ma
Here we need to consider the system as combine, total mass need to be considered.
Total mass, a = m₁+m₂+m₃ = 584 + 838 + 322 = 1744 kg
We need to accelerate the group of rocks from the road at 0.250 m/s²
That is acceleration, a = 0.250 m/s²
Force required, F = ma = 1744 x 0.25 = 436 N
Force must be applied to m₁ to move the group of rocks from the road at 0.250 m/s² = 436 N
I would say Orlando since its near more ocean than Washington. Since Ocean can change weather by making it cold or warm depending on the season.
Answer:
The resultant vector is
.
Explanation:
First, each vector is determined in terms of absolute coordinates:
6-meter vector with direction: 30º north of east.


4-meter vector with direction: 30º east of north.


The resultant vector is obtaining by sum of components:

The resultant vector is
.
Answer:
If a body covers equal displacement in equal interval of time,however small may be the body is said to have uniform velocity. If a body covers in equal displacement in equal interval of time is called variable velocity.
Answer:
The distance from the positive plate at which the two pass each other is 0.0023 cm.
Explanation:
We need to find the acceleration of each particle first. Let's use the electric force equation.


<u>For the proton</u>




<u>For the electron</u>



Now we know that the plate separation is 4.26 cm or 0.0426 m. The travel distance of the proton plus the travel distance of the electron is 0.0426 m.

Both of them have an initial speed equal to zero. So we have:



With this time we can find the distance from the positive plate (x(p)).


Therefore, the distance from the positive plate at which the two pass each other is 0.0023 cm.
I hope it helps you!
