A. Six electrons
B. six protons
C. they are composed of two up quarks and one down quark.
The answer is basis of texture
Answer:
0.76 s
Explanation:
We are given that
Length of rod,L=20 cm=
1 m=100 cm
Mass of rod,M=190 g=
Mass of ball,m=19 g=
Using 1 kg=1000g
We have to find the period if the rod and clay swing as a pendulum.
Moment of inertia of rod-clay=Moment of inertia of rod+moment of inertia of clay


Substitute the values then we get


Now, the center of mass of the combination of the rod and clay is given by

Substitute
=Distance between pivot and the center of the rod
The distance between rod and clay
Using the formula

m
Time period of the oscillation of the system of the rod and the clay is given by

g=
Using the formula
Time period=
Time-period=0.76 s
Hence, the period =0.76 s
Acceleration of the car is 3.375 m/s² and the force of the car moving forward is 5062.5 N
Explanation:
- Acceleration is the rate of change of velocity.
- It is given by the equation, a = change in velocity/time
Here, velocity changes from 0 to 27 m/s and time = 8
⇒ Acceleration = 27 - 0/8 = 27/8 = 3.375 m/s²
- Force is calculated by the equation, F = Mass × Acceleration
- This is based on Newton's second law of motion.
Here, mass of the car = 1500 kg and a = 3.375 m/s²
⇒ Force = 1500 × 3.375 = 5062.5 N
The answer is A. Photosynthesis is caused when plants trap light energy in their leaves and use that energy to change water and carbon dioxide into glucose. Hope this helps :)
