Answer:
Explanation:
To add or subtract two vectors, add or subtract the corresponding components. Let →u=⟨u1,u2⟩ and →v=⟨v1,v2⟩ be two vectors. The sum of two or more vectors is called the resultant. The resultant of two vectors can be found using either the parallelogram method or the triangle method .
Answer:
Transverse wave and Longitudinal wave and Electromagnetic wave
Explanation:
- An inverted wave is a wave in which the vibrations of the particles are perpendicular to the direction of wave motion.
- Longitudinal waves, on the other hand, are waves in which the vibrations of the particles are parallel to the direction of wave motion.
- Electromagnetic waves are waves that do not require medium media for transmission, including radio waves, microwaves, UV lights, etc.
- Most electromagnetic waves are transverse in nature.
We use the following expression
T = 2*pi *sqrt(l/g)
Where T is the period of the pendulum
l is the length of the pendulum
and g the acceleration of gravity
We solve for l
l = [T/2*pi]² *g = [30s/2*pi]²* 9.8 [m/s²] = 223.413 m
The tower would need to be at least 223.413 m high
Explanation :
The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.
Initially, ice is heated until its temperature reaches 
and changes to liquid state.
From the attached graph it is clear that until 
the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.
So, E is the point which shows the gaseous state.
It can either be all of them or just 1 and 3
