Answer:
E = 7.334 KeV
Explanation:
given,
initial energy = 60 keV
Δ x = 30 cm
μ(for soft tissue) = 0.7 cm⁻¹ (taken from table)
E = 60 × 0.1224
E = 7.334 KeV
energy of x-ray photon after travelling through 30 cm soft tissue in body is E = 7.334 KeV
A kind of stimulus is that Optic flow. It occurs as spaceships in Star Wars accelerate to near-light speed and the stars appear to stream outward from the screen's Centre due to centripetal force.
providing the impression of forward momentum. The acceleration vector of an object undergoing UCM is always directed toward the centre because centripetal implies "towards the Centre."m Since the reference frame is spinning, centrifugal force—which is not a real force—occurs as a result of this motion. The centripetal force, which pushes the item in the direction of the circle's Centre and maintains uniform circular motion is called centripetal force, is the real driving force behind uniform circular motion.
The pattern of seemingly moving objects, surfaces, and edges in a visual scene that is brought on by the motion of the observer in relation to the scene is known as optical flow or optic flow. Another way to think of Optic flow is as the distribution of apparent motion velocities of brightness pattern in an image.

Answer:
when your heart rate is not high than normal or lower than normally
Explanation:
Recovery heart rate is when your heart recovers from a certain heart rate eg high heart rate or even low heart rate this means you heart is now functioning normally .
Answer:
F = 3750 N
Explanation:
Given that,
Mass of Donny, m = 75 kg
Initial speed, u = 25 m/s
He suddenly slams on the brakes to avoid hitting a squirrel crossing the road, final speed = 0
Time, t = 0.5 s
We need to find the force the seatbelt exert on him. The force is given by :
F = ma
a is acceleration
So, the force is 3750 N.
