The unit for work J can also be written as Nm. Therefore, it is a derived unit as different SI units are needed to obtain its value. In this case, its derived from force and distance.

What influence do culture and customs have on beliefs about mental disorders? Customs really don't determine what is considered
Mumz [18]

Answer:

The culture of the patient, also known as the consumer of mental health services, influences many aspects of mental health, mental illness, and patterns of health care utilization. One important cautionary note, however, is that general statements about cultural characteristics of a given group may invite stereotyping of individuals based on their appearance or affiliation. Because there is usually more diversity within a population than there is between populations (e.g., in terms of level of acculturation, age, income, health status, and social class), information in the following sections should not be treated as stereotypes to be broadly applied to any individual member of a racial, ethnic, or cultural group.

What is the magnitude of the gravitational force of attraction between two 0.425-kilogram soccer balls when the distance between
Lapatulllka [165]

<u>Answer</u>

4.8212×10⁻¹¹ N


<u>Explanation</u>

The gravitational force F, between 2 masses m₁ and m₂ is given by:

F = (Gm₁m₂)/d²

Where G =  6.673 x 10⁻¹¹ N m²/kg² and d is the distance between the 2 masses.

F = (Gm₁m₂)/d²

   =  (6.673 x 10⁻¹¹ × 0.425 × 0.425)/0.500²

   = 1.2053×10⁻¹¹/0.25

   = 4.8212×10⁻¹¹ N

An electric lamp consumes 60W at 220 volts. How many dry cells of 1.5 V and internal resistance 1 Ohm are required to glow the l
GenaCL600 [577]

Answer:

1. Number of dry cells of 1.5 V required is 40.

2. Number of internal resistance of 1 ohm required is 807

Explanation:

We'll begin by calculating the resistance. This can be obtained as follow:

Power (P) = 60 W

Voltage (V) = 220 V

Resistance (R) =?

P = V²/R

60 = 220² / R

Cross multiply

60 × R = 220²

60 × R = 48400

Divide both side by 60

R = 48400 / 60

R ≈ 807 Ohm

1. Determination of the number of dry cells of 1.5 V required.

Voltage (V) = 220

Dry Cells = 1.5 V

Number of dry cells (n) =?

n = Voltage / Dry cells

n = 60 / 1.5

n = 40

2. Determination of the number of internal resistance of 1 ohm required.

Resistance (R) = 807 Ohm

Internal resistance (r) = 1 ohm

Number of internal resistance (n) =?

n = R/r

n = 807 / 1

n = 807

SUMMARY:

1. Number of dry cells of 1.5 V required is 40.

2. Number of internal resistance of 1 ohm required is 807
