Answer:

Assume that the ball undergoes motion along a straight line. ... F = m A Force = (mass) x (acceleration) The question tells you the mass and the acceleration. All YOU have to do is take the numbers and pluggum into Newton's 2nd law. F = m A = (0.75 kg) (25 m/s²) = (0.75 x 25) kg-m/s² = 18.75 Newtons .

<u>Answer: </u>

A ball of mass 0.75 kilograms needs to be hit so that it accelerates at the rate of 25 meters/second^2 assuming that the ball undergoes motion along a straight line and the mount of Force required is 18.75 newton.

<u>Explanation:</u>

According to Newton`s 2nd  law F=Ma,

where M mass of the object, a- Acceleration due to gravity.

Given-

Mass (m) = 0.75 kg

Acceleration (a) = 25 m/s^2

We know That, Force = mass × acceleration

Substituting the given values , we get

  F = 0.75 × 25

   F= 18.75 N

1. Most waves are caused by vibrations. What motion in a transmitting antenna causes the vibrations that produce radio waves?
morpeh [17]
The answer 1 is
The best-known use of radio waves is for communication; television, cellphones and radios all receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves that can be heard.Electromagnetic radiation is transmitted inwaves or particles at different wavelengths and frequencies.

the answer 2 is

Radio Waves: Instant Communication
Microwaves: Data and Heat

i think the answer number 3 is
It is all about wavelength versus tunnel diameter. The wavelength of GPS is about 20cm it would happily propagate in any normal tunnel if it could get in but the earth and other structures absorb it. AM radio (600kHz - 1500kHz) cannot propagate in any normal tunnel because the wavelength is too long (500m-200m) relative to the diameter, and thus gets reflected at the entrance. FM (100MHz ~ 3m) would propagate and it does for a while but then it suffers reflections

Sedbober [7]

Answer:

The drift velocity of the electrons in this case is c) 5.52 x 10-4 m/s

Explanation:

Hi

First of all, we need to find the volume occupied by 63.3g of copper, so V=\frac{m}{\rho}= \frac{0.0633Kg}{8,900kg/m^{3}} =7.11 \times 10^{-6} m^{3}, then if we assume each atom of copper contributes with one free electron to the material body n=\frac{N_{A}}{V}=\frac{6.02 \times 10^{23} electrons}{7.11 \times 10^{-6} m^{3}} =8.46 \times 10^{28} electrons/m^{3}.

Finally, we apply v_{d}=\frac{I}{nqA}, where A is area so, A=\pi (\frac{d}{2})^{2}= \pi (\frac{0.0016m}{2})^{2}=2 \times 10^{-6} m^{2}, thus v_{d}=\frac{I}{nqA}=\frac{15C/s}{(8.46 \times 10^{28} m^{-3})(1.60 \times 10^{-19} C)(2 \times 10^{-6} m^{2})}=5.50 \times 10^{-4} m/s.

As we can see c. 5.52 x 10-4 m/s is the nearest one.
