How does static work if items are not touching?

Answers

Answer:

Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.

4. Which of the following sets of EM radiation can harm your body cells?
a. Gamma ray, microwaves, infrared
b. Light, ultraviolet, x-ray
c. Microwaves, ultraviolet, infrared
d. Ultraviolet, x-ray, gamma ray

Answers

Answer:

the correct one is D,  

Ultraviolet, x-ray, gamma ray

Explanation:

Electromagnetism radiation are waves of energy that is expressed by the Planck relationship

          E = h f

where h is the plank constant and f the frequency of the radiation.

Also the speed of light is

          c = λ f

         

we substitute

          E = h c /λ

therefore to damage the cells of the body radiation of appreciable energy is needed

microwave radiation has an energy of 10⁻⁵ eV

infrared radiation                E = 10⁻² eV

visible radiation                   E = 1 to 3 eV

radiation Uv                         E = 3 to 6 eV

X-ray                                    E = 10 eV

 

gamma rays                         E = 10 5 eV

therefore we see that the high energy radiation is gamma rays, x-rays and ultraviolet light.

Earth's rotation causes winds to veer to the west or to the east. This is known as the Coriolis effect.

Lesson 1.06



Question 5 options:
True
False

Answers

Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go.  This is known as the Coriolis effect.

If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go.  This is known as the Coriolis force.  It's a"pseudo force", because it doesn't really exist.  It only LOOKS like it's there, because of the Earth's rotation and spherical shape..

The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.

What is the Coriolis effect?

Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.

Characteristics of the Coriolis effect

The Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.

The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.

Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

True or False. When light passes from one medium to another the speed stays constant

Answers

The speed of light is not the same across different medium because of different refractive index. The correct answer is False

The speed of light is approximately 300000000 m/s in a vacuum.

This speed is not the same across different medium because of different refractive index of different medium. Light travels at approximately 300000000 m/s in a vacuum at refractive index of 1

The refractive index of water is about 1.3 which will eventually limit the speed of light. Likewise, the refractive index of glass is about 1.5. This will further reduce the speed at which light travels.

It is therefore False to say that : When light passes from one medium to another the speed stays constant

. A hydraulic lift consists of two cylindrical pistons, one with a radius of 1.5 m and
the other with a radius of 8.0 cm. What force must be applied to the smaller piston if
a crate with a mass of 1.5x103 kg is to be raised on the larger piston?
F=42N,

Answers

Answer:

The force that must be applied to the smaller piston if the crate is to be raised by the larger piston is approximately 42 N

Explanation:

The given parameters of the hydraulic lift are;

The diameter of one of the pistons = 1.5 m

The diameter of the other pistons = 8.0 cm = 0.08 m

The mass of the crate to be lifted with the larger piston, m = 1.5 × 10³ kg

The weight of the mass to be lifted by the larger piston, W₁ = m × g

Where;

g = The acceleration due to gravity = 9.8 m/s²

Therefore;

W₁ = 1.5 × 10³ kg × 9.8 m/s² = 14,700 N

The area of the surface of the circular piston, A = π × r²

Where;

r = The piston's radius

∴ The area of the larger piston with 1.5 m radius, A₁ = π × (1.5 m)² = 7.06868347058 m² ≈ 7.07 m²

A₁ ≈ 7.07 m²

The area of the smaller piston with 0.08 m (8 cm) radius, A₂ = π × (0.08 m)² = 02010619298 m² ≈ 0.02 m²

A₂ ≈ 0.02 m²

The pressure in the fluid of the hydraulic lift is constant, therefore, we have;

The pressure applied to the larger piston with 1.5 m radius, P₁ = The pressure applied to the smaller piston with 0.08 m radius, P₂

∴ P₁ = P₂

[tex]Pressure = \dfrac{Force}{Area}[/tex]

[tex]P_1 = \dfrac{W_1}{A_1} = \ P_2 = \dfrac{F_2}{A_2}[/tex]

[tex]\therefore \dfrac{W_1}{A_1} = \ \dfrac{F_2}{A_2}[/tex]

Where, F₂, represents the force that must be applied to the smaller piston if the crate is to be raised by the larger piston;

[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1}[/tex]

Given that we have the ratio of two areas which have π as a factor, we have;

[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1} = 0.08^2 \times \pi \times \dfrac{14,700}{1.5^2 \times \pi } = 41.81 \overline 3[/tex]

The force that must be applied to the smaller piston if the crate is to be raised by the larger piston, F₂ = 41.81[tex]\overline 3[/tex] N ≈ 42 N.

Kinetic energy? (35 m/s = 78 mph just FYI - use the m/s)

Answers

Answer: 89 J

Explanation:

The kinetic energy of the baseball with the given mass and speed is 89.425 Joules.

What is the Kinetic energy of the baseball?

Kinetic energy is simply a form of energy a particle or object possesses due to its motion.

It is expressed as;

K = (1/2)mv²

Where m is mass of the object and v is its velocity.

Given the data in the question;

Mass of the baseball m = 0.146kgVelocity v = 35m/sKinetic energy of the baseball K = ?

K = (1/2)mv²

K = (1/2) × 0.146kg × (35m/s)²

K = 0.5 × 0.146kg × 1225m²/s²

K = 89.425kgm²/s²

K = 89.425J

A.) 25J

B.) 45 J

C.) 205 J

D.) 225J

Answers

Answer:

Total mechanical energy = 225 J

Speed of duck (v)= 5 m/s

Height of duck from ground (h) = 10 m

Gravitation acceleration (g) = 10 m/s²

Find:

Total mechanical energy

Computation:

Total mechanical energy = Kinetic energy + Potential energy

Total mechanical energy = (1/2)mv² + mgh

Total mechanical energy = (1/2)(2)(5)² + (2)(10)(10)

Total mechanical energy = 25 + 200
