It'll last 20 hours. If it travels 110 miles in one hours, 110 times 20 equals 2,200.
Option (C) is correct that the majority of the elements on the periodic table are metals.

Answer:
11700j
Explanation:
add the two because the plate has to maintain the temp.
2700+9000=11700
Answer:
Moment of inertia of the system is 289.088 kg.m^2
Explanation:
Given:
Mass of the platform which is a uniform disk = 129 kg
Radius of the disk rotating about vertical axis = 1.61 m
Mass of the person standing on platform = 65.7 kg
Distance from the center of platform = 1.07 m
Mass of the dog on the platform = 27.3 kg
Distance from center of platform = 1.31 m
We have to calculate the moment of inertia.
Formula:
MOI of disk =
Moment of inertia of the person and the dog will be mr^2.
Where m and r are different for both the bodies.
So,
Moment of inertia of the system with respect to the axis yy.
