Answer: 1- Issac Newton is the man who discovered gravity. he is important because he found out why everyone was pulled down to the ground. this would later hepl disprove the flat earth theory.
2- Id on't know the vocab words. do those. it'll be the quickest.
3- wieght is how much is being pulled to the ground. mass is how big you are. A pound of rocks and a pound of feathers wiegh the same, but the mass of a pound of feathers will be much greather, as it takes much more feathers to equal a poud than rocks.
Explanation: CHEACK ALL SPELLING!!!! I can't spell that well and my g key doenst like working.
By Newton's second law, the apparent weight of rider coming at rest is <u>3548 N</u>.
According to formula, v = u + at
a = 39.2 m/
Force, F = ma
F = m(a+g)
F = apparent weight
m = mass, given = 65 kg
a = acceleration, given = 39.2 m/
g = 9.8 m/
Put these values in formula, F = m(a+g)
F = 65(39.2+9.8)
F = 3548 N
Therefore, the apparent weight of rider coming at rest is <u>3548 N</u>.

Answer: 0.043mm/s
Explanation:
The drift speed of electron in this wire will ba calculated as:
= I/nqA
= I/nqπr²
= 3.7/[(1.1 × 1^29) × (1.6 × 10^19) × (3.14 × 0.00125²)
= 4.3 × 10^-5
= 0.043mm/s
The drift speed of the electron in this wire is 0.043mm/s.
The amplitude of the wave doesn't depend on its speed
or frequency. Knowing both of those doesn't help you
determine the amplitude at all.
