Answer:

B. A person and the earth

Explanation:

The gravitational force of attraction depends on the masses (M and m) of the object and distance (d) between them.

F = G\frac{Mm}{d^2}

where G is the gravitational constant.

It is given that the distance between first and second objects is same in the given options. This means the gravitational attraction would be largest for the pair which would have largest mass. The Earth has greatest mass followed by a person, then a small bird and an ant has the least mass.

Thus, LARGEST gravitational attraction be found between a person and the earth.

A particle moves in a straight line and has acceleration given by a(t) = 12t + 10. Its initial velocity is v(0) = −5 cm/s and it
soldi70 [24.7K]

Answer:

The position function is s_{t}=2t^3+5t^2-5t+9.

Explanation:

Given that,

Acceleration a =12t+10

Initial velocity v_{0} = -5\ cm/s

Initial displacement s_{0}=9\ cm

We know that,

The acceleration is the rate of change of velocity of the particle.

a = \dfrac{dv}{dt}

The velocity is the rate of change of position of the particle

v=\dfrac{dx}{dt}

We need to calculate the the position

The acceleration is

a_{t} = 12t+10

\dfrac{dv}{dt} = 12t+10

a_{t}=dv=(12t+10)dt

On integration both side

\int{dv}=\int{(12t+10)}dt

v_{t}=6t^2+10t+C

At t = 0

v_{0}=0+0+C

C=-5

Now, On integration again both side

v_{t}=\int{ds_{t}}=\int{(6t^2+10t-5)}dt

s_{t}=2t^{3}+5t^2-5t+C

At t = 0

s_{0}=0+0+0+C

C=9

s_{t}=2t^3+5t^2-5t+9

Hence, The position function is s_{t}=2t^3+5t^2-5t+9.

A long, thin solenoid has 950 turns per meter and radius 3.00 cm. The current in the solenoid is increasing at a uniform rate of
REY [17]

Answer:

Part a)

E = 0.188 \times 10^{-3} N/CPart b)[tex]E = 0.376 \times 10^{-3}N/C

Explanation:

As we know that the magnetic field near the center of the solenoid is given as

B = \mu_0 ni

Also we know by  equation of Faraday's law

EMF induced in the closed loop will be equal to rate of change in magnetic flux

so we have

EMF = A\frac{dB}{dt}

so we have

\int E. dL = \pi r^2 (\mu_0 n \frac{di}{dt})

E. (2\pi r) = \pi r^2 (\mu_0 n \frac{di}{dt})

E = \frac{\mu_0 n r}{2} \frac{di}{dt}

Part a)

At r = 0.500 cm

we have

E = \frac{4\pi \times 10^{-7} (950) (0.500 \times 10^{-2})}{2}(63)

E = 0.188 \times 10^{-3} N/C

Part b)

At r = 1.00 cm

we have

E = \frac{4\pi \times 10^{-7} (950) (1.00 \times 10^{-2})}{2}(63)

E = 0.376 \times 10^{-3}N/C

What’s the answer for this
AlladinOne [14]

Answer:

52.5 m

Explanation:

The displacement is the area under the velocity vs time graph.

From 0 to 5 seconds, the area is the area of the triangle plus the area of the rectangle.

x = ½ (3 s) (15 m/s) + (2 s) (15 m/s)

x = 52.5 m
