what does a steep slope line mean? in science

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.

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

Explanation:

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:

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.

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

Momentum is caclucated using the equation P=mv. Where m is mass and v is velocity.

If you are required to show your work it would be the following:

1400*70=98000 kg*m/s

1300*85=110500 kg*m/s

98000+110500=208500 kg*m/s

209000 kg*m/s

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

Answer:

Light has the unique property that it can be described in physics as both a wave and as a stream of particles called photons

Explanation:

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.

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.
