I need the answer to this question what has the student plotted on the vertical axis?

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.

Given :

Mass of object, m = 15.6 grams.

Volume of object, V = 2 cm³.

To Find :

The density of the object.

Solution :

We know, density of an object is given by :

[tex]\rho = \dfrac{m}{V}\\\\\rho = \dfrac{15.6}{2}\ grams/cm^3\\\\\rho = 7.8\ grams/cm^3[/tex]

Hence, this is the required solution.

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.

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

Answer: B

Explanation: It states they have the same mass so the eliminates the majority of the answers. Density = mass/volume so if sample A & B have the same mass but A is heavier that means A has more volume than sample B

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;

The 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:

Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.

Explanation:  So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.

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.

hydrochloric acid

Explanation:

The compound Mr. Pham's company used is most likely hydrochloric acid.

Hydrochloric acid is a strong acid and it is applied to remove corrosion and rusts from another body.

The acid is capable of dissolving and breaking down the rust and corrosion.

A base does not have this property and would not effectively remove the corrosion.

Sodium hydroxide and lithium hydroxide are bases.

Nitric acid is not as strong as hydrochloric acid.

Explanation:

The law of conservation of charge states that whenever electrons are transferred between objects, the total charge remains the same.

Answer/Explanation:

The weight of an object is defined as the force that is exerted due to the gravitational force.

Mathematically, it can be written as :

W = m g

Where

m is the mass of the object

g is the acceleration due to gravity

Also,  

We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.

The feature of an object that affects its weight are :

Mass of the object

Location of the object

How much force Earth exerts on the object

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

Answer:

Explanation:

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
