Question

Diffferentiare between atmospheric pressure and liquid pressure

Solution 1

Hydrostatic pressure is the pressure exerted by an incompressible fluid (a liquid) at a given point, due to the weight of the fluid above it. Atmospheric pressure is the pressure exerted on a surface by the weight of the atmosphere (a compressible fluid) above it.

Question

A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the density of lead.

Solution 1

Density = mass / volume. Mass = 1587g. Volume = 4.5cm x 5.2cm x 6cm = 140.4 cubic-cm. Mass/volume = 1587/140.4 = 11.3 g/cm^3.

Solution 2

The **density **of** lead **is **11.30 g/cm^3**

__Given the following data:__

- Length = 4.50 cm

- Width = 5.20 cm

- Height = 6.00 cm

- Mass of lead = 1587 g

To find the **density **of** lead**;

First of all, we would determine the** volume** of the block of **lead **by using the formula;

Substituting the values into the formula, we have;

Volume = 4.50 * 5.20 * 6.00

Volume = 140.4 cm^3

Next, we find the **density **of** lead**;

Substituting the values into the formula, we have;

**Density = 11.30 g/cm^3**

Therefore, the **density **of** lead **is **11.30 g/cm^3**

Question

What causes wind to follow patterns

Solution 1

**Answer: Wind follows a pattern because the Earth is spinning in one motion. If we were spinning in one way then another we would have one day go by then the spinning cycle would change and we would have to go through that day all over again, it would not be logical because then we would be in the same season as well, we would be in one season for the rest of our lives until we died. **

Question

How much gravitational force attracts a ball weighing 300 kilograms ?

Solution 1

**Given that,**

Mass of a ball = 300 kg

**To find,**

The gravitational force acting on the ball.

**Solution,**

The force acting on the ball is force of gravity. It is equal to the weight of the ball.

**W = mg**

Substitute the value of m and g in the above formula

W = 300 kg × 10 m/s²

= 3000 N

**Therefore, the ball attracts with a force of 3000 N.**

Question

What amount of current in amperes has the potential to burn internal organs

Solution 1

**Answer:**

4 Amperes

**Explanation:**

At 600 Volts, a current of 4 amperes can pass through the body causing burns to internal organs.

Question

Un automóvil acelera de 0 a 140 km/h en 9.8 segundos, determina su aceleración

Solution 1

**Answer:**

The acceleration is 14.28 km/h^2

**Explanation:**

Step one:

Given data

initial speed u= 0 km/h

final speed v= 140km/h

time t= 9.8 seconds

Required

The acceleration of the car

Step two:

From a= v-u/t

substitute

a= 140-0/9.8

a=140/9.8

a=14.28 km/h^2

Question

A 50gk boy on a rough horizontal ground the coefficeint of static friction is 0.68

Solution 1

**Given that,**

Mass of a boy = 50 kg

The coefficient of static friction = 0.68

To find,

Let us assume we need to find the maximum static friction between the boy and the ground.

Solution,

The formula for the maximum static friction between the two objects is given by :

Where

N is normal force

Substitute all the values,

**Therefore, the maximum static friction between the boy and the ground is 340 N.**
