Multiply the number 4.48E-8 by 5.2E-4 using Google. What is the correct answer in scientific notation?

Physics
1 answer:
Oksi-84 [34.3K]3 years ago
8 0

Answer:

2.32\times 10^{-11}

Explanation:

First number is 4.48\times 10^{-8}

Second number is 5.2\times 10^{-4}

We need to multiply the two numbers.

4.48\times 10^{-8}\times 5.2\times 10^{-4}=(4.48\times 5.2)\times 10^{(-8-4)}\\\\=23.296\times 10^{-12}

In scientific notation : 2.32\times 10^{-11}

Hence, this is the required solution.

“I am sure I will get a good grade on this project. I’ve worked really hard; my teacher will recognize my efforts!” This stateme
Pachacha [2.7K]
The answer would be b., individualism. Femininity is obviously out the picture and decentralization means "The transfer of authority from central to local government. and collectivism is "<span>the practice or principle of giving a group priority over each individual in it." And since the statement says "...my teacher will recognize MY efforts!" and not OUR efforts, then it isn't collectivism.</span>

What is the approximate value of the gravitational force between a 73 kg astronaut and a 7.1×104 kg spacecraft when they're 89 m
Luden [163]

Answer:

F = 4.3671 * 10^{-8}\ Newtons

Explanation:

The gravitational force between two corpses is given by the following equation:

F = GMm/d^2

Where F is the force, G is the gravitational constant

(G = 6.67408*10^{-11}\ m^3kg^{-1}s^{-2}), M and m are the masses of the corpses and d is the distance between them.

So we have that:

F = 6.67408*10^{-11} * 7.1*10^4 * 73/89^2

F = 4.3671 * 10^{-8}\ Newtons

A space probe lands on a newly discovered planet. A small canister is released from the probe and falls a distance of 3 m in 0.5
ivanzaharov [21]

Answer:

24m/s²

Explanation:

Given

Distance S = 3m

Time of fall = 0.5sec

Required

Acceleration due to gravity

Using the equation of motion

S = ut+1/2gt²

Substitute the given values

3 = 0+1/2g(0.5)²

3 = 1/2(0.25)g

3 = 0.125g

g = 3/0.125

g = 24

Hence the value for the acceleration of gravity on this new planet is 24m/s²

How does adding more of a substance affect it's density?
fomenos
I’m going to use molasses as an example of a substance.

The mass and volume both change when changing the amount of molasses.
However, the density does not change. This is because the mass and volume increase at the same rate/proportion!

Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume). Therefore, the spacing between those tiny particles that make up the molasses is constant (does not change).

The size or amount of a material/substance does not affect its density.
