Gamma ray and x Ray I’m pretty sure. Because they have the shortest wavelengths but the highest energy wave. Hope this helped :)

Answer:

The waves with the most higher energy are Gamma rays and X-rays

Explanation:

The electromagnetic spectrum is the distribution of radiation due to the different wavelengths at which it radiates and its different intensities.

The energy of each wavelength can be determined by means of the following equation:

E = h\nu  (1)

but \nu = \frac{c}{\lambda}, therefore:

E = \frac{hc}{\lambda}  (2)

Where h is the Planck constant, c is the speed of light and \lambda is the wavelength.

Radiation is distributed along that electromagnetic spectrum according with the wavelength or frequency. Therefore, the ones with lower wavelength will have higher energy according to equation 2, since they are inversely proportional.

For example, Gamma rays, X-rays, ultraviolet rays, the visible region are the ones with the lower wavelengths and infrared, microwave and radio waves with higher wavelength.

Then, the waves with the most higher energy are Gamma rays and X-rays.

If the velocity of a pitched ball has a magnitude of 44.5 m/s and the batted ball's velocity is 55.5 m/s in the opposite directi
Lelu [443]

Answer:

ΔP = 14.5 Ns

I = 14.5 Ns

ΔF = 5.8 x 10³ N = 5.8 KN

Explanation:

The mass of the ball is given as 0.145 kg in the complete question. So, the change in momentum will be:

ΔP = mv₂ - mv₁

ΔP = m(v₂ - v₁)

where,

ΔP = Change in Momentum = ?

m = mass of ball = 0.145 kg

v₂ = velocity of batted ball = 55.5 m/s

v₁ = velocity of pitched ball = - 44.5 m/s (due to opposite direction)

Therefore,

ΔP = (0.145 kg)(55.5 m/s + 44.5 m/s)

<u>ΔP = 14.5 Ns</u>

The impulse applied to a body is equal to the change in its momentum. Therefore,

Impulse = I = ΔP

<u>I = 14.5 Ns</u>

the average force can be found as:

I = ΔF*t

ΔF = I/t

where,

ΔF = Average Force = ?

t = time of contact = 2.5 ms = 2.5 x 10⁻³ s

Therefore,

ΔF = 14.5 N.s/(2.5 x 10⁻³ s)

<u>ΔF = 5.8 x 10³ N = 5.8 KN</u>

Represent 7468 N with SI units having an appropriate prefix. Express your answer to four significant figures and include the app
Musya8 [376]

Answer:

7.468 kN

Explanation:

Here the force is given in Newton

Some of the prefixes of the SI units are

kilo = 10³

Mega = 10⁶

Giga = 10⁹

Tera = 10¹²

The number is 7468.0

Here, the only solution where the number of significant figures is kilo. If any other prefix is chosen then the significant figures will increase.

1 kilonewton = 1000 Newton

1\ Newton=\frac{1}{1000}\ kilonewton

\\\Rightarrow 7468\ Newton=\frac{7468}{1000}\ kilonewton\\ =7.468\ kilonewton

So, 7468 N = 7.468 kN

The activation of clotting factors will be blocked.
dedylja [7]

With the blocking of activation of clotting factors, the rate of conversion of fibrinogen to fibrin will decrease to a huge extent and this will prevent the clot formation.

Option A

<h3><u>Explanation:</u></h3>

The process of stopping of flow of blood through any wound by formation of a clot is known as blood clotting. The clot in blood is formed by conversion of the fibrinogen protein into its polymer form fibrin which forms a meshwork.

The conversion of fibrinogen to fibrin requires a lot of enzymes and factors present which is required one by one, known as the Cascade theory. Total of 13 factors are required, where there are prothrombin, thromboplastin, and different other factors. Inactivation of any of the 13 factors will lead to less conversion of fibrinogen to fibrin, thereby the rate of conversion will highly decrease.

10points asap <br><br> A force of 30 N acts upon a 7 kg block. Calculate its acceleration.
nekit [7.7K]
Hello! Assuming that the only force acting on the mass is 30N...

Fnet = 30N
Fnet = ma (mass x acceleration)
ma = 30N
a = 30N / m
a = 30N / 7kg
a = 4.2857 m/s^2
a = 4 m/s^2

I hope this helps!
