In Newtonian physics, the acceleration of a body is inversely proportional to mass. In Newtonian rotational physics, angular acceleration is inversely proportional to the moment of inertia of a frame.
The moment of Inertia is frequently given the image I. it's miles the rotational analog of mass. The moment of inertia of an object is a measure of its resistance to angular acceleration. because of its rotational inertia, you want torque to change the angular pace of an object. If there may be no net torque acting on an object, its angular speed will no longer change.
In linear momentum, the momentum p is the same as the mass m instances of the velocity v; whereas for angular momentum, the angular momentum L is the same as the instant of inertia I times the angular pace ω.

Answer: 24.4 degrees to the vertical
Explanation:
Vertical component of raindrop speed = 11m/s
Horizontal component of wind = 5m/s
In this case, all we have to do is to use trigonometric ratios of angles to sides as in a triangle
Doing this, we see that
tan (theta) = 5/11
(Where theta is the angle made with the vertical by the rain after impact)
Tan being opposite/adjacent
Arc sin (5/11) gives us 24.44 degrees to the vertical
Answer:
1.
-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
Explanation:
We are given that magnetic deflection
We have to match each symbol in formula with what it represents.
In this formula
Deflection force
q=Charge of particle
v=Velocity of charge
B=Perpendicular magnetic field strength
Therefore,
1.-Deflection force
2.q-Charge
3.v-Velocity of the charge
4.B-Perpendicular magnetic field strength
Answer:
Explanation:
Discount the time here; it's not important. It doesn't tell you how long it takes the car to stop, it only refers to reaction time, which means nothing in the scheme of things.
The useful info is as follows:
initial velocity = 20 m/s
final velocity = 0 m/s
a = -10 m/s/s
and we are looking for the displacement. Use the following equation:
Δx
where v is the final velocity, v₀ is the initial velocity, a is the deceleration (since it's negative), and Δx is displacement. Filling in:
Δx and
0 = 400 - 20Δx and
-400 = -20Δx so
Δ = 20 meters
