Answer:
3.3*10^-28j
Explanation:
A P E X
The energy of an electromagnetic wave that has a frequency of 5.0 * 10^5 Hz is 3.3 * 10 ^ -28 J
What is Electromagnetic waves ?Electromagnetic waves are the waves that are created as a result of vibration between an electric field and a magnetic field . They are composed of oscillating magnetic and electric field
Energy of Electromagnetic waves can be calculated by
Energy = h * f where h = plank's constant = 6.626 * 10^-34 J s.
f = frequency of electromagnetic waves
given : h = 6.626 * 10^-34 J s.
frequency = 5.0 * 10^5 Hz
Energy of electromagnetic waves = (6.626 * 10^-34 J s) *( 5.0 * 10^5 Hz)
= 33.13 * 10 ^ -29 J
= 3.3 * 10 ^ -28 J

A 16 lb weight stretches a spring 6 inches in equilibrium. It is attached to a damping mechanism with constant c. Find all values of c such that the free vibration of the weight has infinitely many oscillations.
Answer:
[tex]-8<c<8[/tex]
Explanation:

A car starts from rest and reaches a speed of 25m/s in 4 seconds. What is the acceleration?
Also, Calculate the distance the object traveled,
Can y’all help me with this one
Answer:
a = 6.25 m/s/s
d = 50 m
Explanation:
Given:
v1 (initial velocity)= 0 m/s (cz its at rest)
v2 (final velocity)= 25 m/s
t = 4s
a = ?
d = ?
to determine acceleration
a = (v2 - v1)/ t
= (25m/s - 0m/s)/4s
= 6.25 m/s/s
to determine distance traveled
d = 1/2(v1 + v2)t
=1/2(0m/s+25m/s)(4s)
=50 m
Answer:
Answer in explanation.
Explanation:
Using Equation
[tex]v = u + at[/tex]
where v is the final velocity
u is initial velocity
a is acceleration
t is time taken
given u = 0, v = 25, t = 4,
[tex]25 = 0 + 4a \\ 4a = 25 \\ a = 6.25 \frac{m}{ {s}^{2} } [/tex]
Now, using equation
[tex]v {}^{2} = {u}^{2} + 2as[/tex]
where v and u remains the same, a = 6.25 and s is the distance,
[tex](25) {}^{2} = \: {0}^{2} + 2(6.25)s \\ 12.5s = 625 \\ s = \frac{625}{12.5} \\ s = 50m[/tex]

PLEASE ILL GIVE BRAINLIST Which term describes the high point of a transverse wave?
O A. Crest
O B. Compression
O C. Rarefaction
O D. Trough
Answer:
I belive that the answer is the A
Crest describes the high point of a transverse wave. Therefore, the correct option is option A.
Transverse waves are those which oscillate in directions that are opposite to the wave's forward motion. Electromagnetic radiation, seismic waves, or water surface ripples are all examples of transverse waves.
A simple transverse wave can be represented by a sine or cosine curve because any point's amplitude—that are, its distance from the axis—is proportional to the sine (or cosine) associated with that angle. Crest describes the high point of a transverse wave.
Therefore, the correct option is option A.

What does the transfer of energy have to do with natural disasters?
Answer: When an earthquake occurs energy is transferred, from where the rocks break, and travels throughout the world. The bigger the quake the further from the epicentre the waves will travel. There are four types of earthquake wave generated during an earth quake
Explanation:
The intensity of a natural disaster can be determined by the amount of energy transferred due to it.
What is meant by natural disaster ?Natural disasters include calamities with atmospheric, geological, and hydrological causes (such as droughts, earthquakes, floods, hurricanes, and landslides), which can result in fatalities, property damage, and social and environmental disturbance.
Here,
Internal and external forces work together to create natural disasters. The first is internal forces that are caused by the earth's internal heat energy and result in geologic hazards including earthquakes, volcanoes, and tsunamis.
Energy is transferred during an earthquake and propagates throughout the globe from the point at which the rocks split. The waves' distance from the epicenter increases with the size of the earthquake.
During an earthquake, four different kinds of seismic waves are produced. They transfer energy out of the earthquake's epicentre.
Hence,
The intensity of a natural disaster can be determined by the amount of energy transferred due to it.

1 gram of radium is reduced by 3.1 mg in 5 years by alpha decay.
Calculate the half-life of radium.
Answer:
1 gm = 1000 mg
N = No e^-y t where y = lambda the decay constant
N / N0 = .9969
ln .9969 = - y t
-.00310 = - 5 y
y = .00310 / 5 = .000621
So the half-life = .693 / y
T^1/2 = .693 / .000621 = 1116 or about 1120 yrs

Answer:
13 m in the + x direction.
Explanation:
Givens
m1 = m
m2 = 3m
v1= ? = x
v2 = - 3 m/s
v3 = v4 = - 1 m/s
Equation
Let x be the speed of the lighter object before collision.
Momentum before collision = momentum after collision
Solution
mx - 3m * 3m/s = (m1 + m2)*(-1)
m(x - 3*3m/s) = (m + 3m)(-1)
m(x - 9) = - 4m Cancel the ms
x - 9 = 4 Add 9 to both sides
x = 9 + 4
x = 13 m/s

From the question we are told
A constant applied force Fp of 11.0 N pushes a box with a mass=7 kg a distance x=15.0 m across a level floor. The coefficient of kinetic friction between the box and the floor is .110. Assuming the box starts from the rest, what is the final velocity vf of the box at 15.0 m point? If there were no friction between the box and the floor, what applied force F new would give the box the same final velocity?
Generally the equation for the Force is mathematically given as
F_p-\mu mg=ma
Therefore
11-0.110*7*9.8=7*a
a=0.49m/s^2
Using Newtons equation
v^2=u^2+2as
v^2=0+2*0.49*15
v=3.83m/s
Therefore
F=ma
F=0.49*7
F_{new}=3.43N
