Bezzdna [24]

Answer:

4589.05 year

Explanation:

The relation of activity is given by $A=A_0e^{\lambda t}$ we have given $\frac{A}{A_0}=0.574$

Half life $T=5730\ years$

We know that half life $T=\frac{0.693}{\lambda }$

$\lambda =\frac{0.693}{5730}=1.2094\times 10^{-4}\ per\ year$

So $0.574=e^{-1.2094\times 10^{-4}t}$

$e^{1.2094\times 10^{-4}t}=\frac{1}{0.574}=1.742$

${1.2094\times 10^{-4}t}=ln1.742=0.555$

$t=\frac{0.555}{1.2094\times 10_{-4}}=4589.05\ year$

The earth's gravity is pulling on you. Are you pulling on the earth? Explain why or why not.

mel-nik [20]

Answer:

"we both attract each other with the same force but we know that attraction between two bodies depends upon their mass, greater the mass of two bodies is the force of attraction between them"(got this off the internet).

I would like to know why this is the correct answer

Helen [10]

The acceleration of the object if the net force is decreased = 0.13 m/s²

<h3>Further explanation</h3>

Given

A net force of 0.8 N acting on a 1.5-kg mass.

The net force is decreased to 0.2 N

Required

The acceleration of the object if the net force is decreased

Solution

Newton's 2nd law :

$\tt \sum F=m.a$

The mass used in state 1 and 2 remains the same, at 1.5 kg

state 1

ΣF=0.8 N

m=1.5 kg

The acceleration, a:

$\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{0.8}{1.5}\\\\a=0.53`m/s^2$

state 2

ΣF=0.2 N

m=1.5 kg

The acceleration, a:

$\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{0.2}{1.5}\\\\a=0.13~m/s^2$
