Answer:
The weight of an automobile, W = 17640 N
Explanation:
Given that,
The mass of an automobile, m = 1800 Kg
The weight of an object is represented as the gravitational force acting on an object of mass 'm'. It given by the formula
W = m x g newton
Where,
g - acceleration due to gravity.
Substituting the given values in the above equation
W = 1800 Kg x 9.8 m/s²
= 17640 N
Hence, the weight of the automobile, W = 17640 N
Answer:
Number of slices of pizza is 993.
Explanation:
It is given that, in one slice of "everything" pizza there are 650 Calories. The conversion factor from calories to joules is :
1 calorie = 4.184 joules
650 calories = 2719.6 joules
Total energy in the pizza, E = 2700000 J
Let there are n number of slices of pizza. It is given by :

n = 992.79
or
n = 993
So, there are 993 slices of pizza. Hence, this is the required solution.
