Answer:

Halite

Explanation:

The magnitude of the horizontal component of the balls initial velocity if the angle between the horizontal and the direction of the 5.0 meters per second decreases from 30 degrees to 20 degrees is 4.7 m / s

cos θ = Adjacent side / Hypotenuse

θ = 20°

V = 5 m / s

Since the direction of ball makes a right angled triangle with the horizontal,

cos θ = [tex]V_{x}[/tex] / V

[tex]V_{x}[/tex] = cos 20° * 5

[tex]V_{x}[/tex] = 0.94 * 5

[tex]V_{x}[/tex] = 4.7 m / s

The formula used to solve is called as trigonometric ratios formulas. The basic formulae are:

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

Therefore, the magnitude of the horizontal component of the balls initial velocity is 4.7 m / s

The electric field between the disks is 8.43*10^6 N/C

What is electric field of charged spherical spheres ?
A simple application of Gauss' law will yield the electric field of a conducting sphere with charge Q. In the case of a sphere-shaped Gaussian surface with radius r > R, the electric field is directed outward and has the same strength at every point along the surface. Simply multiplying the electric field by the spherical surface's area yields the electric flux.

The electric field is observed to be the same as a point charge Q at the sphere's centre. A Gaussian surface at r R will encompass no charge because all the charge will be on the conducting surface, and by virtue of its symmetry, can be observed to be zero at all places inside the sphere

Diameter of the disks = 1.6cm

Radius of the disks = 1.6/2= 0.8cm= 0.008m

gap between 2 disks d = 1.2mm = 0.0012m

Explanation:

After the first two hours, you have traveled 150km (given) which means that you still have 300km - 150km = 150km left to travel. Since you have already traveled 2 hours, that means you must travel the remaining 150km in 3hours - 2hours = 1hour. Assuming the answer is in km/hour, you will need to travel at a speed of 150km/1h = 150km/h for the remaining of the distance.

The change in the speed of the object is constant with constant increment of 5 m/s.

The change in the speed of an object is the rate at which the distance covered by the object changes with time.

The change in the speed of the object at various time is calculated as follows;

at time, t = 0 second, change in speed (Δv) = 0

at time, t = 1 second, change in speed (Δv) = 5 m/s - 0 m/s = 5 m/s

at time, t = 2 seconds, change in speed (Δv) = 15 m/s - 5 m/s = 10 m/s

at time, t = 3 seconds, change in speed (Δv) = 30 m/s - 15 m/s = 15 m/s

at time, t = 4 seconds, change in speed (Δv) = 50 m/s - 30 m/s = 20 m/s

at time, t = 5 seconds, change in speed (Δv) = 75 m/s - 50 m/s = 25 m/s

      The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force applied on the item determines the object's acceleration.

        The definition of acceleration (symbol: a) in physics or physical science is the rate of change (or derivative with respect to time) of velocity.

       The equation a = v/t denotes acceleration (a), which is the change in velocity (v) over the change in time (t).

     The displacement that an object or particle experiences with respect to time is expressed vectorially as velocity. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed).

         When an item is travelling at a constant speed, its acceleration can be zero. There won't be any acceleration because the speed is constant, hence there won't be any change in speed. Zero acceleration is shown by the graph above.
