Which location, 23 degrees or 48 degrees would experience the same earthquake at stronger intensity?Explain why.​

Answers

Answer:

48 degress

Explanation:

An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce. In the United States, we use the Modified Mercalli Scale. Earthquake intensity is a ranking based on the observed effects of an earthquake in each particular place. Therefore, each earthquake produces a range of intensity values, ranging from highest in the epicenter area to zero at a distance from the epicenter.

A washing machine spin dries clothes. It starts spinning at 20 rad/s and slows down to 8 rad/s while turning through 500 revolutions.
a. What is the angular acceleration?
b. How much time does it take to slow down?

Answers

Answer:

i do not know man

Explanation:

lol

The angular acceleration of the washing machine spin is 53.5 x 10⁻³.

What is meant by angular acceleration ?

Angular acceleration is defined as the time rate of change of angular velocity in a circular motion.

Here,

Initial angular velocity, ω₁ = 20 rad/s

Final angular velocity, ω₂ = 8 rad/s

Angular displacement, θ = 2[tex]\pi[/tex] x no. of revolutions

θ = 2[tex]\pi[/tex] x 500 = 1000[tex]\pi[/tex]

a) Using the equation of circular motion,

ω₂² - ω₁² = 2αθ

Therefore, the angular acceleration,

α = (ω₂² - ω₁²)/2θ

α = (20² - 8²)/2 x 1000[tex]\pi[/tex]

α = 53.5 x 10⁻³ rad/s²

b) Time taken by the machine spin to slow down,

t = (ω₂ - ω₁)/α

t = (20 - 8)/53.5 x 10⁻³

t = 224.2 s

Hence,

a) The angular acceleration of the washing machine spin is 53.5 x 10⁻³.

b) Time taken by the washing machine spin to slow down is 224.2 s.

If the radius of Earth were one half what it is now, and the mass were the same, what would be the value of g?

Answers

Answer:

4 times what it is now.

Explanation:

g=G(M/r^2)

G is constant, so ignore.

We have (1M/0.5r^2), or 4.

Answer:

4g

Explanation:

the equation of g (field gravity)

g = G M/R²

because G (Contant of Gravitasion) and M (Mass of earth) same, them

g2/g1 = R1²/R2²

g1 = g now

g2 = g which the value we looking for

g2/g = 1/(1/2)²

g2/g = 1/(1/4)

g2/g = 4

g2 = 4g

OR

Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and releases more neutrons. The neutrons hits the nuclei of more atoms, splitting them and releasing more energy and neutrons.

(A) The value for the acceleration of the 5 kg rock is the same as the value for the 10 kg rock, but their velocity values are different.
(B) The values for the acceleration and velocity of the 5 kg rock are greater than the values for the 10 kg rock.
(C) The values for the acceleration and velocity of the 5 kg rock are less than the values for the 10 kg rock.
(D) The values for the acceleration and velocity of the 5 kg rock are the same as the values for the 10 kg rock.

Answers

Answer:

D

Explanation:

F=ma

F of 5 kg rock = 49N

F of 10 kg rock = 98 N

Divide by respective masses to get acceleration, and of course you will get 9.8 m/s^2 for both.

Now, use potential energy equals kinetic energy. mgh=(1/2)mv^2 mass cancels out of the equation, since it's on both sides, so we can stop right there. We have algebraically determined that mass does not affect acceleration or velocity!

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:

Answers

Answer:

Centripetal force = 13140 Newton.

Explanation:

Given the following data;

Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg

Velocity = 15m/s

Radius, r = 25m

To find the centripetal force, we would use the following formula:

Centripetal force = mv²/r

Substituting into the equation, we have;

Centripetal force = (1460*15²)/25

Centripetal force = (1460 * 225)/25

Centripetal force = 328500/25

Centripetal force = 13140 Newton.
