Answer:
Volume = 24 cm^3
Explanation:
We recall that the volume of the box is calculated via the formula:
Volume = length * height * width
and that in a product, the number of significant figures for the result should coincide with the number of significant figures of the factor that has the least of them.
In this case, all measures have the same number of significant figures: two. so we calculate the product, and then limit the answer value to exactly two significant figures:
Volume = 4.1 cm * 2.8 cm * 2.1 cm = 24.108 cm^3, which must be rounded to two significant figures as: 24 cm^3
Answer:
a) -35.6°C
b) 237.4 K
Explanation:
To convert temperature from degree celsius to degree fahrenheit, use the formula below:
a) Therefore to convert -32°F to celsius, substitute it into the celsius
b) To covert to the Kelvin scale, use the formula below
Answer:
Frequency, f = 3.24 Hz
Explanation:
Given that,
Mass of the person, m = 78 kg
Mass of the car, M = 2667 kg
Distance, x = 2.35 cm
Let k is the spring constant of the spring. It can be calculated using Hooke's law as :
The frequency of oscillation is given by :
f = 3.24 Hz
So, the frequency with which the car and passenger vibrate on the springs is 3.24 Hz. Hence, this is the required solution.
Seriously. Just fill in the five senses. These include visual, auditory, gustatory, olfactory and touch senses
The basic unit of mass in the International System of Units. or SI, is D. gram.
