It depends how far you travel.

If for instance you travel 1000 miles, then your speed is distance/time = 1000/5 = 200 mph

Answer:

first get a map and show how far you are from your original destination since the destination is not well identified where it is in Michigan so just get an approximate distance and then do the calculations

When a single star with a mass equal to the sun dies, it will become a

maria [59]

When a single star with a mass equal to the sun dies, it will become a: white dwarf.

A star is a giant celestial (astronomical) object which comprises a luminous sphere of plasma bounded together by its own gravitational force.

A single star can be defined as a type of star that moves through space alone.

Generally, a star is mainly composed of two (2) hot gases and these are:

I. Hydrogen (H).

II. Helium (He).

Based on Astronomy, when a star runs out of hydrogen, depending on its mass, it would either turn into any of the following:

A planetary nebula.

A supernova.

A white dwarf.

Similarly, when a single star with a mass equal to the sun dies, it will turn into a white dwarf.

A vector has an x component of -27.5 units and a y component of 41.4 units. Find the magnitude and direction of this vector. mag

evablogger [386]

Answer:

a.) magnitude __49.7__ unit(s)

b.) direction __123.6°_ counterclockwise from the +x axis

Explanation:

Let Vector is v

x-component of Vector v = x = -27.5 units (minus sign indicate that x-component is along the minus x-axis )

y-component of Vector v = y = 41.4 units

Magnitude of v = ?

Direction of v = ?

To find the magnitude of the vector

v = $\sqrt{x^{2}+y^{2} }$

v = $\sqrt{-27.5^{2}+41.4^{2} }$

v = 49.7 units

To find direction

θ = tan⁻¹(y/x)

θ = tan⁻¹(41.4/-27.5)

θ = -56.4°

This Angle is in the clockwise direction with respect to -x axis.

We need to find Angle counterclockwise from the +x axis.

So,

θ = 180° - 56.4°

θ = 123.6°

The given vector is in 2nd quadrant

An air-filled capacitor consists of two parallel plates, each with an area of 7.60 cm2, separated by a distance of 1.80 mm. If a

SOVA2 [1]

Answer:

(a) 9444.4 V/m

(b) 3.72×10⁻¹² F

(c) 6.324×10⁻¹¹ C

Explanation:

(a)

The formula of electric field is given as

E = V/r ......................... Equation 1

Where E = Electric Field, V = Electric potential, r = distance between the plates of the capacitor.

Given: V = 17.0 V, r = 1.8 mm = 0.0018 m.

Substitute into equation 1

E = 17.0/0.0018

E = 9444.4 V/m.

(b)

The formula of the capacitance of a capacitor is given as,

C = ε₀A/d .......................... Equation 2

Where C = Capacitance of the capacitor, ε₀ = permitivity of free space, d = distance between the plates, A = Area of each plate.

Given: A = 7.6 cm² = 0.00076 m³, d = 1.8 mm = 0.0018 m.

Constant: 8.854×10⁻¹² F/m.

Substitute into equation 2

C = 8.854×10⁻¹²(0.00076)/0.0018

C = 3.72×10⁻¹² F.

(c)

The charge stored in a capacitor is given as,

q = CV................... Equation 3

Where q = charge, V = Voltage applied across the plate of the capacitor.

Given: V = 17.0 V, C = 3.72×10⁻¹² F

Substitute into equation 3

q = 17(3.72×10⁻¹²)

q = 63.24×10⁻¹²

q = 6.324×10⁻¹¹ C
