The area under the curve of a velocity vs time graph gives us what?

1 answer:

4 0

The area under the curve of a velocity-time graph gives us the position of an object to find the object's displacement specifically.

Therefore, A: Position of an object is the correct answer.

Aluminum wire 1.00 mm in radius is to be used to construct a solenoid 15.0 mm in radius so that the magnitude of the magnetic fi

Leto [7]

To solve this problem we will proceed to use the equations given for the calculation of the resistance, in order to find the radius of the cable. Once the length is found we can find the number of turns of the solenoid and finally the net length of it

The resistance of the wire is

$R= \frac{\rho L}{A}$

$\rho$ = Resistivity

L = Length

A = Cross-sectional Area

That can be also expressed as,

$R = \frac{\rho L}{\pi r^2}$

Rearranging the equation for the length of the wire we have

$L= \frac{R\pi r^2}{\rho}$

$L= \frac{3\Omega \pi(1*10^{-3})}{2.655*10^{-8}\Omega \cdot m}$

$L = 354.8m$

The number of turns of the solenoid is

$N = \frac{L}{2\pi r} \rightarrow$ Denominator is equal to the circumference of the loop

$N = \frac{354.8}{2\pi(15*10^{-3})}$

$N = 3766$

Finally the Length of he solenoid is

$l = N (\phi)$

Where \phi is the diameter of wire

$l = N (2r)$

$l = (3766)(2*(1*10^{-3}))$

$l = 7.532m$

Therefore the length of the solenoid is 7.532m

Aaron walks 5 miles every day for exercise, leaving his front porch at 5:00 am. And returning to his porch at 6:00 am. What is t

taurus [48]

Answer:

Total displacement = 0

Explanation:

He lives his front porch and still returns to his front porch.

Now, displacement is a vector quantity and as such, it is the distance between the initial point of movement and the final point of movement.

In this case the initial point is the same as the final point and thus the displacement is zero.

The constellation Canis Minor has a binary star system consisting of Procyon A and Procyon B. Procyon A, at 3×1030kg, has 2.5 ti

denis-greek [22]

This question involves the concepts of Newton's Law of Gravitation and mass.

The force on Procyon A from Procyon B will be "equal" to the force on Procyon B from Procyon A, which has a value of "3.75 x 10²⁶ N".

Applying Newton's Law of Gravitation, we can find the force on Procyon A from Procyon B, which is equal to the force on Procyon B from Procyon A:

$F=\frac{Gm_1m_2}{r^2}$

where,

F = force = ?

G = universal gravitational constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = mass of Procyon A = 3 x 10³⁰ kg

m₂ = mass of Procyon B = (2.5)(3 x 10³⁰ kg) = 7.5 x 10³⁰ kg

r = distance between them = 2 x 10¹² m

Therefore,

$F=\frac{(6.67\ x\ 10^{-11}\ N.m^2/kg^2)(3\ x\ 10^{30}\ kg)(7.5\ x\ 10^{30}\ kg)}{(2\ x\ 10^{12}\ m)^2}$

F = 3.75 x 10²⁶ N

A stone is thrown horizontally at 30m/s from a tall cliff.

Jobisdone [24]

x(2) = 30(2) = 60 m

y(2) = ½(-9.8)2² = -19.6 m

x(4) = 30(4) = 120 m

y(4) = ½(-9.8)4² = -78.4 m

x(6) = 30(6) = 180 m

y(6) = ½(-9.8)6² = -176.4 m

x(8) = 30(8) = 240 m

y(8) = ½(-9.8)8² = -313.6 m

x(10) = 30(10) = 300 m

y(10) = ½(-9.8)10² = -490 m

soldier1979 [14.2K]

Answer:

C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.

Explanation:

Due to it being an invasive specie (naturally found in South Asia), and also one of the five largest species of snakes in the world, the Burmese pythons lack natural predators in this new territories.

The Burmese viper is also an opportunistic hunter and would eat anything it can overpower, it easily made a wide range of food varieties in these swamps.
