A. What is the mass of a book that weighs 3.20 N in the laboratory?
B.In the same lab, what is the weight of a dog whose mass is 14.0 kg?
A. 3.20 N /9.81= .3261977574 kg
B. 14.0 kg (9.81)= 137.34N
*Done it on Pearson and it's right*
A. Ah, the eternal struggle of books trying to lose weight! Well, if the book weighs 3.20 N, we can calculate its mass using Newton's Second Law (F = ma). Since weight is the force due to gravity (in N), we can divide the weight (3.20 N) by the acceleration due to gravity (standardly taken as 9.8 m/s²). So, the mass of the book would be approximately 0.33 kg. That's one light read!
B. Woof! Dogs and their mass, always making us fetch for answers. If the mass of the dog is 14.0 kg, we can find its weight by multiplying the mass (14.0 kg) by the acceleration due to gravity (9.8 m/s²). So, the weight of the dog would be approximately 137.2 N. That's one heavy pup, but I bet he's still a "paws-itive" force in your life!
A. To find the mass of the book, we can use Newton's second law of motion, which states that weight (W) is equal to the mass (m) multiplied by the acceleration due to gravity (g). The value of acceleration due to gravity is approximately 9.8 m/s^2 on Earth.
Given:
Weight of the book (W) = 3.20 N
Acceleration due to gravity (g) = 9.8 m/s^2
We can use the formula W = m * g to find the mass (m) of the book:
m = W / g
Substituting the given values:
m = 3.20 N / 9.8 m/s^2
m ≈ 0.326 kg
Therefore, the mass of the book is approximately 0.326 kg.
B. To find the weight of the dog, we can use the same formula as before: W = m * g.
Given:
Mass of the dog (m) = 14.0 kg
Acceleration due to gravity (g) = 9.8 m/s^2
We can substitute the given values into the formula:
W = 14.0 kg * 9.8 m/s^2
W ≈ 137.2 N
Therefore, the weight of the dog is approximately 137.2 Newtons.
A. To determine the mass of the book, you can use the equation:
Weight = mass * acceleration due to gravity
In this case, the weight of the book is given as 3.20 N. The acceleration due to gravity on Earth is approximately 9.8 m/s^2. Rearranging the equation, we can solve for mass:
mass = weight / acceleration due to gravity
Plugging in the values, the mass of the book would be:
mass = 3.20 N / 9.8 m/s^2
B. To calculate the weight of the dog, you can use the same equation:
Weight = mass * acceleration due to gravity
In this case, the mass of the dog is given as 14.0 kg. Again, the acceleration due to gravity on Earth is approximately 9.8 m/s^2. Plugging in the values, the weight of the dog would be:
Weight = 14.0 kg * 9.8 m/s^2
