Answer:
57 N
Explanation:
Were are told that the force
of gravity on Tomas is 57 N.
And it acts at an inclined angle of 65°
Thus;
The vertical component of the velocity is; F_y = 57 sin 65
While the horizontal component is;
F_x = 57 cos 65
Thus;
F_y = 51.66 N
F_x = 24.09 N
The net force will be;
F_net = √((F_y)² + (F_x)²)
F_net = √(51.66² + 24.09²)
F_net = √3249.0837
F_net = 57 N
Answer:
Energy stored in the capacitor will be 
Explanation:
We have given edge length of capacitor = 
So area A = 1.2×1.2 = 1.44 
Separation is given as d 1 mm = 
We know that capacitance is given by 
Voltage is given as V = 12 volt
We know that energy stored is given by 
Given: Mass m = 44 Kg; Velocity v = 10 m/s
Required: Kinetic energy K.E = ?
Formula: K.E = 1/2 mv²
K.E 1/2 (44 Kg)(10 m/s)²
K.E = 2,200 Kg.m²/s²
K.E = 2,200 J Answer is A
A.kinetic energy for it an example of wood.
Answer:
human cheek cell has got a nucleus, rbc doesnot
human cheek cell is found in the cheeks n made there whereas rbc is made in the bonemarrow and found in blood
human cheek cell serves the function of supplying nutrition to cheek by simply exchange while rbc transports oxygen around the body..
cheek cell can reproduce rbc cannot asit is non nucleated.The epithelial cells in the lining of the mouth are referred to as basal mucosa and divide roughly every 24 hours. They can easily be obtained through a simple swab or a mouth rinse. The cheek cell is very simple, but it contains the entire genetic makeup of the person's body. For this reason, cheek cells are frequently used to establish paternity and other investigations involving DNA. More recently, researchers have discovered that the cheek cell can be used to measure a person's likelihood of having high blood pressure.
A human cheek cell is thin, flat and irregularly shaped and has a large nucleus that contains the DNA. Its plasma membrane helps the cell to maintain suitable temperature while giving it its shape. Since it is selectively permeable, it only allows certain molecules into and out of the cell. Its cytoplasm contains water that dissolves nutrients and enzymes. It is an animal cell so it is different from plant cell.and the difference will be same as that with animal cell
