One of the main arguments that animal rights advocate present is that animals have rights because they are capable of suffering.

Animal rights are ethical visions founded on the trust that animals deserve the space to live their own lives without being affected by mortal interests.

Humans have to always give freedom to animals for their living without their personal interests.

The animal is capable to suffer this is an argument that comes always on the animal rights sheet.

Hence the option B is correct.

Answer:

W = P * t      work = work/time * time

t = W / P       time required

t = 2000 kg * 9.8 m/s2 * 28 m / P = 549,000 J / 13000 J/s

t = 42.2 sec

Note:  1 kW = 1000 J/sec

Time  required for an elevator to lift a 2000 kg load up 28 m from the ground level, if the motor can produce 13 kW of electric power will be 42.22 seconds .

The time rate of doing work or delivering energy is called Electric   Power

electric Power  can be calculates by

electric  Power = Work done / time

Given :

mass (m) = 2000 kg

height (h) = 28m

electric  power (P) = 13 kW =   13 * 10^3  

acceleration due to gravity (g) = 9.8 m/s^2

Since , the load has been taken to a certain height , hence work must be done and that work done is stored in the form of Potential Energy

Work done = m* g * h

                  = 2000 * 9.8 * 28

13000 = 2000 * 9.8 * 28 / time

Time = 2000 * 9.8 * 28 / 13000

Time = 42.22 seconds

Time  required for an elevator to lift a 2000 kg load up 28 m from the ground level, if the motor can produce 13 kW of electric  power will be 42.22 seconds .

Answer:

Mental and physical health is fundamentally linked. There are multiple associations between mental health and chronic physical conditions that significantly impact people’s quality of life, demands on health care and other publicly funded services, and generate consequences to society.  The World Health Organization (WHO) defines: health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.   The WHO states that “there is no health without mental health.”

Nowhere is the relationship between mental and physical health more evident than in the area of chronic conditions. The associations between mental and physical health are:

1. Poor mental health is a risk factor for chronic physical conditions.

2. People with serious mental health conditions are at high risk of experiencing chronic physical conditions.

3. People with chronic physical conditions are at risk of developing poor mental health.

The social determinants of health impact both chronic physical conditions and mental health. Key aspects of prevention include increasing physical activity, access to nutritious foods, ensuring adequate income and fostering social inclusion and social support. This creates opportunities to enhance protective factors and reduce risk factors related to aspects of mental and physical health.

Understanding the links between mind and body is the first step in developing strategies to reduce the incidence of co-existing conditions and support those already living with mental illnesses and chronic physical conditions.

Answer:he's not applying force or motion

Explanation:

p=f & m

The strength of the electric field will be 0.75 NC⁻¹ . Electric force F acted per unit positive electric charge q  is known as the strength of the electric field.

The electric, or Coulomb, force F exerted per unit positive electric charge q at any place,  can be used to calculate the strength of an electric field E at any position.

It is given by;

E = F/q

The given data in the problem is;

q is the value of  charge=6. 0 × 10⁻⁴C

F is the electric force = 4. 5 × 10⁻⁴ N

E is the strength of electric field=?

The electric field strength is found by the formula;

[tex]\rm E=\frac{F}{q} \\\\ \rm E=\frac{4.5 \times 10^{-4}}{6 \times 10^-4} \\\\ \rm E= 0.75\ N/C[/tex]

Hence the strength of the electric field will be 0.75 NC⁻¹ .

The statements 'much interstellar dust comes from stellar atmospheres', 'molecular clouds are where stars are born' and 'coronal gas is ejected from supernova explosions' are TRUE. Molecular clouds are stars in formation.

Molecular clouds are regions into the space where celestial bodies (stars) are born in a galaxy.

The formation of stars always occurs within these molecular clouds, especially in the disk-shaped area of spiral galaxies.

Molecular clouds can be considered areas into space that are formed by very cold and dark matter.

Weight is essentially just a measurement of the force of gravity, so you can use this equation.

F = mg

Force = Mass × Acceleration due to Gravity

F = 19kg × 9.8m/s^2. (Acceleration due to Gravity on Earth.)

F = 186.02N

The frequency of the light source is 1.5 x 10¹⁵ Hz.

The frequency of the light source is determined using the following equations;

c = fλ

where;

c is speed of light

f is the frequency

λ is the wavelength

f = (3 x 10⁸) / (2 x 10⁻⁷)

f = 1.5 x 10¹⁵ Hz

Thus, the frequency of the light source is 1.5 x 10¹⁵ Hz.

m = 40g/1000g × 1kg = 0.04kg

F = 18N

using the formula for Force

F = ma

Then making acceleration the subject of the formula; you Will get

a = F/m
