6. What makes an object float rather than sink?

Answers

Answer 1

Answer: An object will float in any solution rather than sink, when the density of the object is less than that of the solution in which it is floating. This statement does not mean that the object has to be lighter in weight than the fluid in which it is floating. A great example is a ship floating in water. I hope the answer helps you.

A student increases the temperature of a 556 cm3 balloon from 278 K to 308 K. Assuming constant pressure, what should the new volume of the view be? 320 cm3
501 cm3
1232 cm3
616 cm3

Answers

To solve this we assumethat the gas inside the balloon is an ideal gas. Then, we can use the ideal gasequation which is expressed as PV = nRT. At a constant pressure and number ofmoles of the gas the ratio T/V is equal to some constant. At another set ofcondition of temperature, the constant is still the same. Calculations are asfollows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 = 308 K x 556 cm³ / 278 K

V2 = 616 cm³

Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. Which is most likely to result in the greatest amount of error in their scientific experiment?

Answers

In doing research or experiments, it is necessary that the variables applied on the test subjects are the same. In the problem, the factor that will most likely result in the greatest amount of error will be the plant subjects. Different plants have different growth rates, and their growth can be affected by the many variables such as sunlight, disturbance, location, etc.

Answer:

One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table.

The mass of a lamb that weighs 110 n is about a. 1 kg.
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above

Answers

A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.

What are Mass and Weight?

The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.

In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.

According to the question, the given values are :

Weight, w = 110 N and,

Taking value of g = 10 m/s²

As we know that :

w = m × g

110 = m (10)

m = 11 kg

Hence, the mass of the lamb will be 11 kg.

g = 10 m/s²
w = 110 N

w = m x g
110 = m x 10
110 = 10 m
m = 110/10 = 11 kg
