An object is placed 12 cm from a convex mirror with a focal length of 5.0 cm. please help.

Explanation:

Given that,

Mass of a skier, m = 55 kg

The vertical distance between start and finish is 10 m.

(a) The potential energy of a skier is given by :

[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]

(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,

[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]

Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

A person’s blood type depends on the type of protein marker, called an  Antigen, found on the cell membranes of the red blood cell.

A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.

Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.

The ABO system distinguishes 4 major blood types:

Chemical symbol for nitrogen is :

Answer:

942.75J

Explanation:

Change in thermal energy is equal to the mass of the given substance times the specific heat capacity times the temperature change.

We've already been given the specific heat capacity, the mass as well as the initial and final temperatures.

So change in temperature will be 35° - 20° = 15°

Thermal energy change = 15 × 15 × 4.19

The final answer is 942.75J

F = 6.0 x 10⁻⁸ N

Given

mass of 2 dump trucks = 1500 kg

distance = 50 m

Required

Gravitational force

Solution

Newton's Gravity Law:  

[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]

with F = gravitational force,  

G = gravitational constant,  

m1, m2 = mass of object,  

r = distance between two objects.  

Input the value :

F = (6.67.10⁻¹¹N.m² / kg² x 1500²) :  50²

F = 6.0 x 10⁻⁸ N

I don't know if I can think of another 5 right now. but I hope this helps.

This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds. The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second)

Centi is the metric prefix for 0.01

Answer:

[tex]\mu =0.169704 Ns/m^2[/tex]

Explanation:

From the question we are told that

Area of plate[tex]a=1m^2[/tex]

Angle of inclination [tex]\theta=60 \textdegree[/tex]

Velocity [tex]v=0.75m/s[/tex]

Thickness of oil [tex]t=2mm[/tex]

Weight of plate [tex]w=90N[/tex]

Generally the equation for shear force is mathematically given by

[tex]F=mgsin45 \textdegree[/tex]

[tex]F=90sin45 \textdegree[/tex]

[tex]F=63.639N[/tex]

[tex]F=\mu* \frac{v}{t}[/tex]

[tex]F=\mu* \frac{0.75}{2*10^-^3}[/tex]

[tex]\mu* \frac{0.75}{2*10^-^3}=63.639N[/tex]

[tex]\mu =\frac{63.639}{375}[/tex]

Therefore viscosity is given by

[tex]\mu =0.169704 Ns/m^2[/tex]

Answer: Cross-cutting features are always younger than the surrounding rock.

When material erodes before sediment is deposited on it, a geologic gap results.

Explanation:

The options include:

1. An unconformity is created when lava pours out on Earth’s surface.

2. Faults are the result of volcanic activity.

3. Intrusions and extrusions are sedimentary formations.

4. Cross-cutting features are always younger than the surrounding rock.

5. When material erodes before sediment is deposited on it, a geologic gap results.

The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.

Other tools that can help scientist with relative dating are:

• Cross-cutting features are always younger than the surrounding rock.

• When material erodes before sediment is deposited on it, a geologic gap results.

The law which describes the behavior of gases in the Sun is Gay-Lussac's Law

Explanation:

The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;

Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;

P ∝ T

The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;

P = K·T

∴ P/T = K (Constant)

[tex]\therefore \dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}[/tex]
