The moon has a mass of 7.34 . 102 kg and a radius of 1.74 . 106 meters. If you have a mass of 66 kg,
how strong is the force between you and the moon?
Answer:
[tex]F=1.06\times 10^{-18}\ N[/tex]
Explanation:
Given that,
Mass of the Moon, [tex]M=7.34\times 10^2\ kg[/tex]
Mass of the person, m = 66 kg
The radius of Moon, [tex]r=1.74\times 10^6\ m[/tex]
We need to find the force between the person and the Moon. The formula for the gravitational force is given by :
[tex]F=G\dfrac{Mm}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{7.34\times 10^2\times 66}{(1.74\times 10^6)^2}\\\\=1.06\times 10^{-18}\ N[/tex]
So, the required force is [tex]1.06\times 10^{-18}\ N[/tex].

Showing results for a 4 olm and 8 ohm resistor are connected in series. The current through the 4 olm resistor is 2 amps. What is the current through the 8 olm resister?
Plzzzz help 20 points
Answer:
Let R1= resistance of 4ohms
R2= resistance of 8ohms
Equivalent resistance R will be
R=R1 + R2
=> 4+8=12ohms
The current through the two resistors will be the same since they are connected in series. Notwithstanding, the voltage will drop to appreciate the change.
Explanation:
The value of current from the 8-ohm resistor is the same as in the 4-ohm resistor which is equal to the 2 Amp.
What is resistance?Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
When two resistors are connected to the series in that condition the value of current is the same in both the resistors.
While the value of resistance is different in both the different.
Hence the value of current from the 8-ohm resistor is the same as in the 4-ohm resistor which is equal to the 2 Amp.

Find the volume of an object with a density of 3.1 g/mL and a mass of 12 g.
Answer:
Density = Mass/Volume => Volume = Mass/Density = 12/3.1 = 3.87ml
Explanation:
Answer:
3.9 mL
Explanation:
To find the volume of an object using its mass and density, we can use the following formula:
Volume = Mass/Density
Volume = 12/3.1
Volume ≈ 3.9
Therefore, the volume of the object is 3.9 mL.

A family is skating at an ice rink. The 58.2 kg mother is holding the
hand of her 35.5 kg daughter. The father grabs his wife's free hand and pulls horizontally with a constant force of 100. N. Assume that the skates glide without friction on the ice and that the family's hands andarms approximate ideal strings. How much net force does the daughter experience?
Answer:
When I got this question I had to draw it out so if you have to do that, draw 3 stick figures holding hands, one representing the mother, father, and daughter. Then you write their weights on top of them and then draw an arrow pointing from the father to the mother.
Explanation:
use this formula :
[tex]a_{y}[/tex] = [tex]\frac{Fdadshandy}{msys}[/tex]
then you fill it in :
[tex]a_{y}[/tex] = [tex]\frac{100N}{35.5kg+58.2kg}[/tex]
[tex]a_{y}[/tex] = [tex]\frac{100N}{93.7kg}[/tex]
[tex]a_{y}[/tex] = [tex]1.0672[/tex] [tex]m/s^{2}[/tex]
then you multiply that with the daughters weight :
[tex]T_{2} x= m_{2} a_{y}[/tex]
[tex]T_{2} x = 35.5kg (1.0672 m/s^{2})[/tex]
[tex]T_{2} x = 37.89N[/tex]
and that's the answer :) : 37.89N

A statue of a great baseball player weighs 2400 N and has a base that is 4 m x 2 m. What is the pressure the statue exerts on the floor?
Answer:
300N/m²
Explanation:
Pressure is calculated using the formula;
Pressure = Force/Area
Given
Force = 2400N
Area = 4m×2m = 8m²
Substitute the given parameters into the formula as shown;
Pressure = 2400/8
Pressure = 300N/m²
Hence the pressure the statue exerts on the floor is 300N/m²

If 100.0 g of a substance releases 45 kJ of energy as it cools from 13.0°C to –15.0°C, what is the specific heat capacity of the substance?
Answer:
16,071.42J/kgKExplanation:
The formula for expressing the quantity of heat released is expressed as;
Q = mcΔt
m is the mass of the substance = 100g - 0.1kg
c is the specific heat capacity of the substance
Δt is the change in temperature = 13 -(-15) = 28°C
Substitute and get c;
45000 = 0.1c(28)
2.8c = 45000
c = 45000/2.8
c = 16,071.42J/kgK
Hence the specific heat capacity of the substance is 16,071.42J/kgK

if a 60 kg person was standing on a platform at the surface of saturn and they jumped, they would have to push with a force greater than..?
Answer:
A 60 kg person standing on a platform at the surface of Saturn and they jumped, they would have to push with a force greater than 540 N
Explanation:
The gravitational attraction between an object on the surface of a planet and the planet is given by the weight of the object
Therefore the force needed to be applied for an object to lift off the surface of a planet = The weight of the object
The weight of the object on the surface of a planet = m × g
Where;
m = The mass of the object
g = The strength of gravity on the planet's surface in N/kg
The given parameters are;
The mass of the person standing on a platform at the surface of Saturn, m = 60 kg
The strength of gravity on the surface of Saturn = 9 N/kg
Therefore, we have;
The weight of the person = The force greater than which the person would have to push on the surface of Saturn so as to Jump = The weight of the person on the surface of Saturn = 60 kg × 9 N/kg = 540 N
Therefore, for a 60 kg person standing on a platform at the surface of Saturn and they jumped, they would have to push with a force greater than 540 N.

Metamorphic rock occurs when you take any other type of rock and put them under ________ and ______________, and they twist and meld together.
Answer:
This question appear incomplete
Explanation:
This question appear incomplete because of the absence of options. However, metamorphic rocks are rocks that are formed from other pre-existing rocks under heat and pressure (both are usually high), causing them to twist and melt together. Metamorphism simply means a change in form of something and that's what happens here also.

77. Two blocks, with masses m1 = 400 g and m2 = 600 g, are connected by a string and lie on a frictionless tabletop. A force F = 3.5 N is applied to block m2. Find the acceleration of each object.
Answer:
See the answers below. And the free body diagrams attached.
Explanation:
To solve this problem, we must build a free body diagram, where we show the forces acting on a body, first for the m2 body, where the force of 3.5 [N] acts to the right. In such a way that a reaction force is presented in the opposite direction due to the string tied between both bodies, we will call this force T1.
Now using Newton's second law, which is defined as the sum of forces equal to the product of mass by acceleration, we can determine an equation as a function of T1.
∑F = m*a
[tex]3.5 -T_{1}=0.6*a_{2}[/tex]
We have an equation with two unknowns, in such a way we must perform a second free body diagram for the body with mass m1, to acquire the additional equation.
∑F =m₁*a₁
[tex]T_{1}=0.4*a_{1}[/tex]
By kinematics we know that if the string tied to Body 2 moves a distance, the part of the string at the end tied to body 1 will move the same distance. This same analysis is valid for velocities and accelerations.
This is the accelerations a1 and a2 are equal. Now equalizing both equations.
[tex]3.5-0.4*a_{1}=0.6*a_{2}\\but\\a_{1}=a_{2}\\3.5-0.4*a_{1}=0.6*a_{1}\\a_{1}=3.5[m/s^{2} ][/tex]
The acceleration of each block connected by the given string is 3.5 m/s².
The given parameters;
mass of the first block, m1 = 400 g = 0.4 kgmass of the second block, m2 = 600 g = 0.6 kgapplied force, F = 3.5 NThe net force on the blocks is calculated as follows;
[tex]\Sigma F = ma\\\\F - T = m_2a\\\\F - m_1(a -g)= m_2a\\\\g = 0 \ , \ in \ horizontal \ direction\\\\F - m_1a = m_2 a\\\\F = m_2 a + m_1 a\\\\F = a(m_1 + m_2)\\\\a = \frac{F}{m_1 + m_2} \\\\a = \frac{3.5 }{0.4 + 0.6} \\\\a = 3.5 \ m/s^2[/tex]
Thus, the acceleration of each block connected by the given string is 3.5 m/s².

Answer:
i) 2Mg + O₂ + Δ Heat → 2MgO + Δ Energy
ii) The aqueous solution does not change in the color of the blue litmus paper and the blue litmus paper remains blue in color
The aqueous solution formed using the product (MgO) turns the red litmus paper blue
Explanation:
i) Magnesium easily burns in air or oxygen when heated to form a white powder of magnesium oxide. The burning (reaction) of magnesium in air is an exothermic reaction that involves the release of heat and light
The burning of magnesium wire is given by the following chemical reaction;
2Mg + O₂ + Δ Heat → 2MgO + Δ Energy
ii) When magnesium oxide is mixed with water if forms magnesium hydroxide Mg(OH)₂ as shown in the following chemical reaction;
MgO + H₂O → Mg(OH)₂
Magnesium hydroxide is basic and therefore it will turn red litmus paper blue and it does not change the color of the blue litmus paper.
