Gamma rays are far more energetic than radio waves as they have a higher frequency (they wiggle more). this higher energy can ionise atoms in our body. ionisation of molecules in your DNA can cause mutations, some of which can lead to cancer.

Airplane start with initial speed

v_i = 0

now the takeoff velocity is given as

v_f = 300 km/h

v_f = 83.33 m/s

acceelration is given as

a = 1 m/s^2

now we have

v_f - v_i = at

from above equation we have

83.33 - 0 = 1(t)

t = 83.33 s

Airplane start with initial speed

v_i = 0

now the takeoff velocity is given as

v_f = 300 km/h

v_f = 83.33 m/s

acceelration is given as

a = 2 m/s^2

now we have

v_f - v_i = at

from above equation we have

83.33 - 0 = 2(t)

t = 41.7 s

A circular saw spins at 6000 rpm , and its electronic brake is supposed to stop it in less than 2 s. As a quality-control specia
Alona [7]

Answer:

a. yes

Explanation:

The initial speed of the circular saw is:

\dot n_{o} = \frac{6000}{60} \,\frac{rev}{s}

\dot n_{o} = 100\,\frac{rev}{s}

Deceleration rate needed to stop the circular saw is:

\ddot n = -\frac{100\,\frac{rev}{s} }{2\,s}

\ddot n = - 50\,\frac{rev}{s^{2}}

The number of turns associated with such deceleration rate is:

\Delta n = \frac{\dot n^{2}}{2\cdot \ddot n}

\Delta n = \frac{\left(100\,\frac{rev}{s} \right)^{2}}{2\cdot \left(50\,\frac{rev}{s^{2}} \right)}

\Delta n = 100\,rev

Since the measured number of revolutions is lesser than calculated number of revolution, the circular saw meets specifications.

Which interaction does not take place due to field forces?
amid [387]

The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

<h3>What is the gravity law?</h3>

Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.

This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.

In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.
