T = 0.017 s
From the foot to the brain is almost the same as the height. We are not given the height of the woman, but to find "about" how much time, we need a height to work with.
She *could* be 1.7 m <- height = distance
Formula for speed, where k = speed, d = distance, t = time
k = d/t
Rearrange to solve for time:
t = d/k
Substitute known values:
t = (1.7 m) / (100 m/s)
Solve:
t = 0.017 s
Therefore, it takes about 0.017s for the impulse to travel from the foot to the brain.
Answer:
What are the different personal protective equipment?
Personal protective equipment, commonly referred to as “PPE”, is equipment worn to minimize exposure to a variety of hazards. Examples of PPE include such items as gloves, foot and eye protection, protective hearing devices (earplugs, muffs) hard hats, respirators and full body suits. Understand the types of PPE.
The angle between the two vectors of the same magnitude would be 120 degrees to have the resultants the same.
answer: 120 degrees
Answer:
Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil.
Newton's first law states that an object at rest will stay at rest and an object in motion will stay in motion. So when the car is not moving, the dice will hang directly downwards, being pulled by down by gravity and up by the force normal created of the mirror, equally. But if you start to move forward, then the dice must react in some way, because it is being affected by motion. So the dice will now gravitate towards the back of the vehicle.
You don't notice it but your body is also pulled toward the back of the vehicle. The difference is that you can see the dice. In fact, when you first start to accelerate in your car, you can feel the pull into your seat, but soon you get used to it, and that is what's called relativity.
So the you and the dice are being pulled toward the back of the vehicle, and you can calculate how powerful that force is using F=ma
