Answer:

For electrostatic paint to be applied, the vehicle needs to be grounded and positively charged. This creates a magnetic attraction to the negatively charged paint. Due to this charge, when the paint leaves the nozzle, it is attracted to the vehicle's charge and will stick to it.

Explanation:

The electric force is small in comparison because charges are VERY small but the

gravitational force has to do with the mass of the Earth and Moon.

unperscriebed drugs can e harmful to your body

Explanation:

Answer: b

Explanation:

Ec= (1/2)m × v^2

By the formula, you can see that the bigger the mass, the bigger the Cinetic Energy.

b: b; its mass is smaller

Between ball B and ball C, ball B has LESS potential energy because its mass is smaller.

A potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched.

Potential energy is given by formula.

[tex]P.E= m*g*h[/tex]

Since, P.E is directly proportional to mass. Thus, the ball having smaller mass will have the less P.E.

Thus, option b is correct.

Answer:

27.1m/s

Explanation:

Given parameters:

Height of the building  = 30m

Initial velocity  = 12m/s

Unknown:

Final velocity  = ?

Solution:

We apply one of the kinematics equation to solve this problem:

         v²  = u²  + 2gh

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

h is the height

          v²   = 12²  + (2 x 9.8 x 30)

          v  = 27.1m/s

Answer:

58.3333333

miles

Explanation:

Answer:

Thus, each atom or ion must contain 16 protons. We are told that the ion also has 14 neutrons, meaning the mass number of the ion is 16 + 14 = 30 Because the ion has 16 protons and 19 electrons, its net charge is -3.

Answer:

The answer should be C

Explanation:

Answer:

Explanation:

Factors that affect the moment of a force are;

The magnitude of force applied is directly proportional to the moment of force in that for a perpendicular distance d, increased in force applied will result to a higher moment of force. When the perpendicular distance from the pivot is decreased while the force applied remains constant, the moment of force decreases.

Explanation:

Answer:

1800J

Explanation:

Step one:

given data

mass of bullet m= 3g= 0.03kg

initial velocity u = 400m/s

final velocity v= 200 m/s

Step two:

1.The bullet's lost kinetic energy went inside the tree.

2. The energy transferred is computed as

= initial KE- KE final

Initial KE= 1/2mu^2

Initial KE= 1/2*0.03*400^2

Initial KE= 1/2*0.03*160000

Initial KE= 1/2*4800

Initial KE= 2400J

KE final= 1/2mv^2

KE final= 1/2*0.03*200^2

KE final= 1/2*0.03*40000

KE final= 1/2*1200

KE final= 600J

KE transferred = 2400-600

KE transferred= 1800J

Answer:

The answer is below

Explanation:

The maximum height (h) of a projectile with an initial velocity of u, acceleration due to gravity g and at an angle θ with the horizontal is given as:

[tex]h=\frac{u^2sin^2\theta}{2g}[/tex]

Given that the two projectile has the same height.

[tex]For\ the\ first\ projectile\ with\ an\ angle\ \60^0 \ with\ the\ horizontal\ and initial\ velocity\ u_1:\\\\h=\frac{u_1^2sin^260}{2g} =\frac{0.75u_1^2}{2g} \\\\For\ the\ second\ projectile\ with\ an\ angle\ \30 \ with\ the\ horizontal\ and initial\ velocity\ u_2:\\\\h=\frac{u_2^2sin^230}{2g} =\frac{0.25u_2^2}{2g}\\\\\frac{0.25u_2^2}{2g}=\frac{0.75u_1^2}{2g}\\\\0.25u_2^2=0.75u_1^2\\\\\frac{u_1^2}{u_2^2} =\frac{0.25}{0.75} \\\\\frac{u_1^2}{u_2^2}=\frac{1}{3} \\[/tex][tex]\\\frac{u_1}{u_2}=\sqrt\frac{1}{3}[/tex]

Answer:on Planet X on which an object weighs 300 N if it weighs 98 N on Earth? ... How are weight, mass, and acceleration due to gravity related

Explanation:

Answer:

Yes,in fact visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets', called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).

Answer:

60m/s

Explanation:

Given parameters:

Acceleration  = 2m/s²

Time  = 30s

Unknown:

Change in velocity  = ?

Solution:

Acceleration is the rate of change of velocity with time.

Mathematically;

         Acceleration  = [tex]\frac{Change in velocity }{Time }[/tex]

Now,

 Change in velocity  = Acceleration x time

So,

  input the parameters and solve;

 Change in velocity  = 2 x 30  = 60m/s

Answer:

The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.

Explanation:

Given;

angle of projection, θ = 45°

initial speed of the projectile, u = 25 m/s

horizontal distance traveled by the projectile, x = 50 m

The time taken for the daredevil to travel the 50 m horizontally is calculated as;

[tex]t =\frac{X}{u_x}[/tex]

where;

[tex]u_x[/tex] is the horizontal component of the velocity = uCosθ

[tex]t =\frac{X}{u Cos \ \theta} \\\\t =\frac{50}{25 \times Cos(45)} \\\\t= \frac{50}{17.678} \\\\t = 2.83 \ s[/tex]

Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.

Answer:

A. 12

Explanation:

Answer:

The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases.
