The acceleration due to gravity on Jupiter is 24.79 m/s²,
compared to 9.8 m/s² on Earth ... a ratio of about 2.53 .

So if a person or object were somehow transported to Jupiter,
he/it would weigh

(2.53) times (Earth weight)

there.

A simple pendulum consists of a brass sphere of mass m = 1 kg suspended on a string of length L ≈ 1 meter. The pendulum oscillat

hram777 [196]

Answer:

2. Using a shorter string of length L ′ ≈ 0.25 meters

5. Using a shorter string of length L ′ ≈ 0.5 meters

Explanation:

The period of a pendulum is given by

$T=2\pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum

g is the acceleration due to gravity

We see from the formula that the period of the pendulum depends only on its length, not on its mass or its amplitude of ocillation. Therefore, the only alterations that can change the period of the pendulum are the ones where its length is changed.

Moreover, we notice that the period is proportional to the square of the length: this means that in order to decrease the period of the pendulum (the problem asks us which alterations will reduce the period of the pendulum from 2 s to 1 s), the length of the pendulum should also be reduced.

Therefore, the only alterations that will reduce the period of the pendulum are:

2. Using a shorter string of length L ′ ≈ 0.25 meters

5. Using a shorter string of length L ′ ≈ 0.5 meters

What is an Ion and what does it do? (as much detail as you can put it into please)

user100 [1]

Answer:

Explanation:

Ions are substances the have lost or gained a certain amount of electrons. This makes them either positively or negatively charged.

They are charged particles.

Every atom is made up of protons, neutrons and electrons.
They are the three fundamental particles in any atom
The protons and neutrons are located in the central part called the nucleus of an atom. It is a simple tiny space.
Protons are positively charged particles. Neutrons do not carry any charges. Therefore, the nucleus is negatively charged.
Electrons are negatively charged particles. They occupy the bulk volume of an atom.

Every atom is neutral and the number of protons and electrons are the same. The equal number of protons and electrons balances to attain neutrality of an atom.

Electrons are very easy to lose since they occupy the outermost shell.

When an atom loses an electron, the number of protons is more than electrons. Therefore, it becomes positively charged. Hence, its is called an anion.
An atom can also gain an electron, the electron number will be more than the protons. They then become negatively charged and are called cation.

Cations and ions are substances that are produced to attain a special type of bonding called electrovalent bonding.

Oppositely charged substances attracts one another.

When jumping straight down, you can be seriously injured if you land stiff-legged. One way to avoid injury is to bend your knees

nexus9112 [7]

(a) The man comes to a halt in 1.99 ms = 1.99 × 10⁻³ s, so his average acceleration slowing him from 6.33 m/s to a rest is

a = (6.33 m/s - 0) / (1.99 × 10⁻³ s) ≈ 3180 m/s²

so that the average net force on the man during the landing is

F = (70.8 kg) a ≈ 225,000 N

i.e. with magnitude 225,000 N.

(b) With knees bent, the man has an average acceleration of

a = (6.33 m/s - 0) / (0.147 s) ≈ 43.1 m/s²

and hence an average net force of

F = (70.8 kg) a ≈ 3050 N

(c) The net force on the man is

∑ F = n - w = m a

where

n = magnitude of the normal force, i.e. the force of the ground pushing up on the man

w = the man's weight, m g ≈ 694 N

m = the man's mass, 70.8 kg

g = mag. of the acceleration due to gravity, 9.80 m/s²

a = the man's acceleration

Using the acceleration in part (b), we have

n = m g + m a = m (g + a)

n = (70.8 kg) (9.80 m/s² + 43.1 m/s²) ≈ 3740 N
