Answer:
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.
This is an example of negative acceleration. It's also an example of simultaneous cardiovascular and muscle fatigue.
Answer:
B. I, III and IV
Explanation:
The strength of the magnetic field generated by a solenoid is given by the following formula:
B = μ₀NI/L
where,
B = Magnetic Field
μ₀ = Permeability of Free Space
N = No. of Coils
I = Current Magnitude
L = Length of Coil
Strength is also directly proportional to size of the core.
So, to increase the magnetic field strength we can:
1- The number of Loops
2- Increase the amount of Current (for same length)
3- Decrease the length (for same number of loops)
4- Increase Size of Core
So, the correct answer is:
<u>B. I, III and IV</u>
Answer:
a) 0.323m/s b) 54.278 m/s
Explanation:
The shell is moving upward with a speed of 17m/s
1.7s after it was launch
Using equation of motion on a straight line,
Vfinal = Vintial + acceleration due to gravity *time
Where V represent the speed(velocity)
Vinital = V(at 1.7s) - 9.81* 1.7
Vinital = 17 - 16.677
a) Vinital = 0.323m/s
b) using the same equation,
V(after 5.5s) = Vinital + 9.81*5.5s
Vafter5.5s = 0.323 + 53.955
V after 5.5s = 54.278m/s
