The Hubble Space Telescope has a mass of 1.16*10^ 4 kg and orbits the Earth at an altitude of 5.68 * 10 ^ 5 above Earth's surface. Relative to infinitydetermine the potential energy the telescope at this location. Would the formula be Ep=-Gm1m2/r or positive G since it’s relative to infinity
Answer:
[tex]E=8.13\times 10^{12}\ J[/tex]
Explanation:
Given that,
The mass of a Hubble Space Telescope, [tex]m_1=1.16\times 10^4\ kg[/tex]
It orbits the Earth at an altitude of [tex]5.68\times 10^5\ m[/tex]
We need to find the potential energy the telescope at this location. The formula for potential energy is given by :
[tex]E=\dfrac{Gm_1m_e}{r}[/tex]
Where
[tex]m_e[/tex] is the mass of Earth
Put all the values,
[tex]E=\dfrac{6.67\times 10^{-11}\times 1.16\times 10^4\times 5.97\times 10^{24}}{5.68\times 10^5}\\\\E=8.13\times 10^{12}\ J[/tex]
So, the potential energy of the telescope is [tex]8.13\times 10^{12}\ J[/tex].

An upright object 2.80 cm tall is placed 16.0 cm away from the vertex of a concave mirror with a center of curvature of 24.0 cm. What is the focal length of this mirror?
Answer:
f = 12 cm
Explanation:
Center of Curvature:
The center of that hollow sphere, whose part is the spherical mirror, is known as the ‘Center of Curvature’ of mirror.
The Radius of Curvature:
The radius of that hollow sphere, whose part is the spherical mirror, is known as the ‘Radius of Curvature’ of mirror. It is the distance from pole to the center of curvature.
Focal Length:
The distance between principal focus and pole is called ‘Focal Length’. It is denoted by ‘F’.
The focal length of the spherical (concave) mirror is approximately equal to half of the radius of curvature:
[tex]f = \frac{R}{2}[/tex]
where,
f = focal length = ?
R = Radius of curvature = 24 cm
Therefore,
[tex]f = \frac{24\ cm}{2}[/tex]
f = 12 cm

An empty water tank has a rectangular base with side lengths of 1.2 m and 2.3 m. The weight of the tank applies a pressure of 350 Pa to the surface it is resting on. What is the weight of the tank?
Answer:
Weight = 966 Newton.
Explanation:
Given the following data;
Length = 1.2 m
Width = 2.3 m
Pressure = 350 Pa
To find the weight of the tank;
We know that weight is the force of gravity acting on an object multiplied by its mass.
Weight = mg = force
Hence, we would determine the force using the parameters that were given.
But we would first determine the area of the rectangular tank.
Area of rectangle, A = length * width
A = 1.2 * 2.3
A = 2.76 m²
Mathematically, pressure is given by the formula;
Pressure = force/area
Force = pressure * area
Substituting into the formula, we have;
Force = 2.76 * 350
Force = 966 Newton
Therefore, the weight of the tank is 966 Newton.

. Calculate the equivalent resistance of the circuit.
c. Calculate the current through the battery.
d. How much current is passing through each resistor
[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
1. Calculate the equivalent resistance in the circuit :
In the given diagram, the resistors are in series connection,
So equivalent resistance = sum of resistance of both resistors.
[tex] \large \boxed{R_{eq} =R_1 +R_2 }[/tex]
[tex]R_{eq} = 480 + 360[/tex][tex]R_{eq} = 840 \: ohms[/tex]Therefore, Equivalent resistance = 840 ohms.
2. Calculate the current through the battery :
[tex] \boxed{ \mathrm{current = \dfrac{potential \: \: difference}{resistance} }}[/tex]
[tex]i = \dfrac{120}{840} [/tex][tex]i = \dfrac{1}{7} [/tex][tex]i = 0.142 \: Amperes[/tex]Hence, current through the battery = 0.142 A
3. How much current is passing through each resistor :
Since the resistors are joined in series connection, the current flowing through each resistor will be equal = 0.142 Amperes.

Explanation:
Which of the following is a property of an ionic compound?
A
has a low boiling point
B
forms molecules
C
is soft and flexible
D
conducts electricity when aqueous
Answer:
D
Explanation:
ionic compounds conduct electricity when molten or dissolved in water. ionic compounds conduct electricity when dissolved in water because water molecules are attracted to ions, this weakens the strong electrostatic forces of attraction between the oppositely charged ions. thus, ions are pulled away from the lattice structure and the remaining compound dissolves in water to form aqueous solution. The presence of free moving ions enables the ionic compound to conduct electricity.
