Use. Weight = (mass)x(accel of gravity).
It'll be somewhere around approx roughly about in the neighborhood of 9.706667m/sec^2 .
The 1st example is NOT a longitudinal wave
Explanation:
Waves are periodic disturbance of the space that travel carrying energy but not matter.
Depending on their vibration, waves are classified into two types:
- Transverse waves: in transverse waves, the vibration of the wave occurs in a direction perpendicular to the direction of propagation of the wave. Examples of transverse waves are electromagnetic waves.
- Longitudinal waves: in longitudinal waves, the vibration of the wave occurs in a direction parallel to the direction of propagation of the wave (back and forth), creating regions of higher particle density (compressions) and lower particle density (rarefactions). Examples of longitudinal waves are sound waves.
In this problem we have four options given:
- The first picture represents a transverse wave, because the vibration of the robe is up and down, while the wave propagates on the left-right direction
- The second picture represents a sound wave, which is a longitudinal wave
- The 3rd picture represents a longitudinal wave, since the vibration of the slinky is back and forth along the direction of propagation
- The 4th picture also represents a sound wave, which is longitudinal
Therefore, the only wave which is not longitudinal is the one in the 1st picture.

Answer:
a) x component = -31.25 km/hr
b) y component = 46.64 km/hr
Explanation:
Given data:
A position is 4km north and 2.5 km east to B
Ship A velocity = 22 km/hr
ship B velocity = 40 km/hr
A velocity wrt to velocity of B
putting respective value to get velocity of A with respect to B
a) x component = -31.25 km/hr
b) y component = 46.64 km/hr
Answer:
0
Explanation:
Suppose this is for Excel. You can hide a row or a column by right-clicking on that row/column header and select row height or column width. After that simply input in 0 and click OK. The row or column will be hidden in the end, just like using a Hide command.
Answer:
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
Unit: Pascal (Pa)
1Pa = 1N/m^2
