Answers

1) Weight can be measured in pounds.

2) A bowling ball has more mass than a basketball.

3) A bowling ball weighs more than a basketball.

4) Weight can be measured with a scale.

5) Objects have the same mass regardless of where they are

6) Mass can be measured with a balance.

Explanation

1) Weight can be measured in pounds.

Pound is a unit of weight. It is a Latin word from the term libra, so it is abbreviated as Lb. It is a unit of weight equal to 16 oz.

2) A bowling ball has more mass than a basketball.

A bowling ball is a piece of sporting equipment used to hit bowling pins in the sport of bowling. The mass of bowling ball is 7.25748kg while that of a basketball is around 3.40194kg to 3.85554kg

3) A bowling ball weighs more than a basketball.

It weighs about 16 pounds while a basketball weight about 7.5 - 8.5 pounds.

4) Weight can be measured with a scale.

When different objects are suspended along a uniform spring, it can be calibrated to measure weights on a millimeter scale.

5) Objects have the same mass regardless of where they are

Mass is the quantity of matter in a substance. It is the particles that make up an object. So, this cannot change. It is not like weight where the gravity keeps on changing hence contributing to the change in weight.

6) Mass can be measured with a balance.

The instrument that is used to measure mass is called a weighing balance. So, mass is measured using a balance.

Explanation :

Mass of an object is the amount of matter present in it while weight is the force exerted on the body by virtue of gravity i.e W = F = mg

(1) Mass can't be measured in newtons. It can be in kg or grams.

(2) Weight can be measured in pounds. 1 pound = 4.44 Newton.

(3) A bowling ball has more mass than a basketball. The mass of basketball is approximately 3.5 kg while that of the bowling ball is 7.25 kg.

(4)  A bowling ball weighs more than a basketball. This is because the mass of the bowling ball is more.

(5) Mass can't be measured with a balance. If we are measuring with balance, gravity will always act.

(6) Weight can be measured with a scale. If an object is held along a spring, it is used to measure weight.

(7) Objects have the same mass regardless of where they are. The mass remains constant everywhere.

(8) Objects do not weigh the same regardless of where they are. This is because the value of acceleration due to gravity varies with location. So, the value of weight is different.

The statements that are true for mass and weight are :

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
