Answer:

A “frame of reference” is a standard relative to which motion and rest may be measured; any set of points or objects that are at rest relative to one another enables us, in principle, to describe the relative motions of bodies.

Explanation:

When you see a ball roll down a street, you can tell the ball is moving because the frame of reference is the streets, whatever may be on the side of the roads, or the Earth. All of these are frames of reference. All measurements of motion will be compared to a frame of reference.

Recall that

v² - u² = 2 a ∆x

where u and v are initial and final velocities, respectively; a is acceleration; and ∆x is the distance traveled (because the skater moves in only one direction).

So we have

(5.8 m/s)² - (8.8 m/s)² = 2 a (6.0 m)

a = ((5.8 m/s)² - (8.8 m/s)²) / (12 m)

a = -3.65 m/s²

Which interaction does not take place due to field forces?

amid [387]

The interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

<h3>What is the gravity law?</h3>

Gravity law is a well-established scientific theory that states objects can attract each other according to their masses.

This theory (gravity law) was developed by Sir Isaac Newton to explain the movement of objects.

In conclusion, the interaction that does not take place due to field forces is the interaction between a pen and paper while you write.

A piece of charcoal used for cooking is found at the remains of an ancient campsite. A 1.09 kg sample of carbon from the wood ha

fgiga [73]

Answer:

t = 17199 years

Explanation:

given,

mass of sample = 1.09 Kg

Activity of living material = 15 decays / min /g

Activity of living material = 15 x 1000 decays /min /kg

Activity of living material per 1.09 kg A = 1.09 x 15 x 1000 decays / min

Activity of after time t is A ' = 2020

half life = 57300 years

desegregation constant

λ = 0.693 / 5700

$A'= A e^{-\lambda\ t}$

$A'= 1.09 \times 15 \times 1000 e^{-\lambda\ t}$

$2020= 1.09 \times 15 \times 1000 e^{-\dfrac{0.693}{5700}\times t}$

$0.124=e^{-\dfrac{0.693}{5700}\times t}$

taking ln both side

$\dfrac{0.693}{5700}\times t = 2.09$

t = 17199 years

How would the earth move if the sun suddenly disappeared

Lerok [7]

Just a guess without asking Google, that without the sun's gravity holding us in orbit, we would end up drifting whatever direction we were headed as it disappeared?
