Waves are created on the surface of water when we drop a stone into it. Similarly you must have seen the waves generated on a string when both its ends are held in hand and it is shaken. Light is also a type of wave called the electromagnetic wave. Gamma rays, X-rays, ultraviolet rays, infrared rays, microwave and radio waves are all different types of electromagnetic waves. Astronomical objects emit these waves and we receive them using our instruments. All our knowledge about the universe has been obtained through these waves. Gravitational waves are a very different type of waves. They have been called the waves on the fabric of space-time. Einsteine predicted their existence in 1916. These waves are very weak and it is very difficult to detect them. Scientists have constructed extremely sensitive instruments to detect the gravitational waves emitted by astronomical sources. Among these, LIGO (Laser Interferometric Gravitational Wave Observatory) is the prominent one. Exactly after hundred years of their prediction, scientists detected these waves coming from an astronomical source. Indian scientists have contributed significantly in this discovery. This discovery has opened a new path to obtain information about the Universe. i. Which type of wave a light ray is ? (1 marks) ii. What type of rays are Gravitational waves called ? (1 marks) iii. Why are the gravitational waves difficult to detect ? (1 marks) iv. Give any four examples of electromagnetic waves.

I just need a little starter for this paragraph!
Answer:
The north part of the compass needle is attracted to the magnetic south pole of Earth, which is also known as the geographical north pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.

What is 2.34x10^3x5.1x10^-2 in significant figures.
Answer:
5 significant figures
Explanation:
As the question does not state any term in 'significant figures', I will provide the number and the number of significant figures.
First of all, the number. 2.34 × 10³ = 2340, and 5.1 × 10^-2 = 0.051, therefore. 2340 × 0.051 = 119.34.
This will be equal to 5 significant figures.

The values of gravitational force and gravitational constant become same or equal when product of masses involved equals the square of distance between them.
a leaver raised 500N lode using 200N effort. if load distance and effort distance are 20 cm and 60 cm respectively, calculate mechanical advantage, velocity ratio and efficiency of this lever.
Answer:
Ans:
Explanation:
MA=L/E=500N/200N=5/2
VR=ED/LD=60cm/20cm=3
Thus, Efficiency=(Ma*100%)/VR=83.34%

On a fishing trip you catch a bass, a rock cod, and a salmon with masses of 1.07 kg, 6.0 kg, and
6.05 kg, respectively. What is the total mass of your catch with the proper number of significant
figures?
The total mass of your catch is 13.1 kg
Since you have three fishes a bass, a rock cod, and a salmon with masses of 1.07 kg, 6.0 kg, and 6.05 kg, respectively,
The total mass of your catch = mass of bass + mass of rock cod + mass of salmon
= 1.07 kg + 6.0 kg + 6.05 kg
= 13.12 kg
Since the total mass of your catch is 13.12 kg and we have three catches with two catches to two decimal places and one catch to one decimal place.
We cannot have more decimal places in our answer than the number of decimal places in the number with the least number of decimal places.
Since the least number of decimal places is in the mass of the rock cod which is 6.0 kg, the total mass of our catch is thus 13.1 kg to one decimal place.
So, the total mass of your catch is 13.1 kg

Temp-Kelvin(K)Mass-KgDistance=meter(m)Force-Newton(N)A box is 300 kg & it covers the area of 150 m2 find the pressure exerted by the box in the ground.
Answer:
If we assume that the box is a cube with 150 m² surface area
Area of 1 face = 150 m² / 6 = 25 m²
The box will exert a downward force of
Force = mass * acceleration due to gravity
Force = 300 kg * 9.81 m/s² N
Force = 2943 N
The box exerts a pressure ( force / unit area) = 2943 N / 25 m²
Pressure = 117.7 N/m²

Anything that displaces fluid is acted on by an upward force equal to the weight of the displaced fluid.
Describe a procedure the student could use with the lab setup shown in order to determine the average velocity of the marble as it travels down the inclined ramp. Include what variables would need to be measured and how to measure them.
Variables - Initial position, Final position, Distance between Positions, Time.
Instruments - Ruler (Distance between Positions), Chronometer (Time)
Average Velocity is equal to the change in Position divided by Time. Since Incline is a Straight Line, then Position Change and Traveled Distance are the same. In this case, we need to define Initial and Final Position of the marble, and then we have to measure the distance between these Points.
Distance between Initial and Final Position can be measured by a Ruler, whereas Time can be measured by a Chronometer.
In a nutshell, Initial and Final Position and Time are variables needed to be measured. Besides, Distance between Initial and Final Position can be found by means of a Ruler, and Time is found with the help of a Chronometer.
