Answer:

False

Explanation:

hertz the SI unit of frequency, equal to one cycle per second.

I can certainly think of a graph of a wave-like quantity (like maybe the frequency deviation of an FM-modulated carrier) where the amplitude of the graph would have the units of Hertz. But then, I've been an Electrical Engineer for almost 50 years, and that would be overthinking it.

For YOUR purposes, here on Brainly, the far-better choice is FALSE.

A stuntman drives a car with a mass of 1500 kg on a drawbridge. The car accelerates with a constant force of 10,000 N. While he
Viktor [21]

Answer:

1.77 m/s^2

Explanation:

There are two forces acting on the car along the direction parallel to the incline:

- The driving force of 10,000 N, which pushes forward

- The component of the weigth of the car parallel to the incline, which pulls backward

The component of the weight of the car parallel to the incline is:

W_p = mg sin \theta=(1500 kg)(9.8 m/s^2)( sin 30^{\circ})=7350 N

So now we can apply Newton's second law to find the acceleration of the car:

F-W_p = ma\\a=\frac{F-W_p}{m}=\frac{10000 N-7350 N}{1500 kg}=1.77 m/s^2

A 100-watt lightbulb radiates energy at a rate of 100 J/s. (The watt, a unit of power, or energy over time, is defined as 1 J/s.
fomenos

Answer:

N=2.18\cdot 10^{20}photons/s

Explanation:

The energy of a photon is: E=h\nu=h\frac{c}{\lambda} when h is the Planck constant.

h=6.63\cdot 10^{-34}Js    

c=3.8\cdot 10^{8}m/s

Then, we calculate the energy of a photon with a wavelength equal to 550 nm.

E= 4.58\cdot 10^{-19}J

To find the number of photons we can use this equation:

N=\frac{P}{E}=\frac{100}{4.58\cdot 10^{-19}}=2.18\cdot 10^{20} photons/s

Have a nice day!

A 5.0-kilogram box is sliding across a level floor. The box is acted upon by a force of 27 newtons east and a frictional force o
marshall27 [118]

Answer:

The magnitude of the acceleration of the box is 2 m/s².

Explanation:

Given:

Mass of the box, m=5.0 kg

Force acting towards east, F=27 N

Frictional force acting towards west, f=17 N

Let the acceleration be a m/s².

Now, net force acting on the box towards east is given as:

F_{net}=F-f=27-17=10\textrm{ N}

From Newton's second law of motion,

F_{net}=ma\\10=5.0\times a\\a=\frac{10}{5.0}=2\textrm{ }m/s^2

Therefore, the magnitude of the acceleration of the box is 2 m/s².
