Because we should convert units within the metric system
<h2>
Density of the unknown liquid is 771.93 kg/m³</h2>
Explanation:
An empty graduated cylinder weighs 55.26 g
Weight of empty cylinder = 55.26 g = 0.05526 kg
Volume of liquid filled = 48.1 mL = 48.1 x 10⁻⁶ m³
Weight of cylinder plus liquid = 92.39 g = 0.09239 kg
Weight of liquid = 0.09239 - 0.05526
Weight of liquid = 0.03713 kg
We have
Mass = Volume x Density
0.03713 = 48.1 x 10⁻⁶ x Density
Density = 771.93 kg/m³
Density of the unknown liquid is 771.93 kg/m³
Answer:
The acceleration of the skateboard is -9.65 m/s².
Explanation:
Given that,
Mass of teenager = 72 kg
Force 
Mass of skateboard = 2.8 kg
Suppose, the determine the numerical value for the magnitude of the acceleration of skateboard
We need to calculate the acceleration of skateboard
Using balance equation
Put the value into the formula
Hence, The acceleration of the skateboard is -9.65 m/s².
Answer:
35.20 m
Explanation:
By the law of conservation of energy we have,
where m= mass of the skier, h= 3.00 m
D= horizontal distance=13.9 m
H= maximum height attained
Also, the horizontal distance covered by the skier is
D=vt
thus, height H in terms of D is given by
H=35.20 m
The parts of the cell are mitochondria, lysosomes, ribosomes etc. Their functions are as follows :
(1) Vesicle is a one of the large structure within the cell. Its function is to transfer materials out of the cell.
(2) Mitochondria is also called the power house of the cell. Its function is to break down sugar to supply energy for the cell.
(3) Lysosomes are the suicidal bag of the cell. It breaks down waste and other materials of the cell.
(4) Endoplasmic reticulum helps to produce, process and transport proteins in vesicles to the Golgi apparatus.
