Answer:
Explanation:
Given data :
Length of rubber tube = 13.6m
Mass of rubber tube = 0.750 kg
mass of object = 740 kg
gravitational acceleration = g = 9.8 m/s²
Solution:
First we will find mass per unit length of the rubber tube μ.
μ = 13.6/0.750
= 18.133 kg/m
tension in tube T = mg = 740×9.8
= 7252 N
now we have the values of T and μ we can find the speed v.
v = √T/μ
v = 19.998 m/s
= 13.6/19.998
t = 0.68 s
Answer:
1. False
2. Fats
3. False
Explanation:
MyPlate is an initiative from the United States Department of Agriculture that is designed to help Americans improve their eating habits throughout their lifetimes. Every meal matters. The five food groups represented in My Plate include vegetables, grain, dairy, protein foods, and fruits.
Calories are a source of energy for the human body. So, the more active a person is, the more energy he would need to be supplied to him in form of calories. The less active a person is, the fewer calories he would need.
Explanation:
Below is an attachment containing the solution.
Answer:
The object distance is 92 cm.
Explanation:
let v be the image distance and h be the height of the image, let u the be the object distance and H be the height of the object.
then, the magification of the mirror is given by:
m = -v/u and m = h/H
so, -v/u = h/H
u = -v×H/h
= -(-4.6)×(82)/(4.1)
= 92 cm
Therefore, the object distance is 92 cm.
Answer:
c)From high potential to low potential.
Explanation:
Given that
current is flowing through resister.
As we know that those quantity have direction as well as magnitude then these are called vector quantity and those quantity have only magnitude then they called scalar quantity.
As we know that current have direction as well as magnitude so current is a vector quantity.
Current flows from high potential to low potential.
