Answer:
Hey buddy, here is your answer. Hope it helps you.
Explanation:
Yes, weight of a body is not constant, it varies with the value of acceleration due to gravity, g. Weight of a body is zero, when it is taken to the centre of the earth or in the interplanetary space, where g=0. Mass is the total matter in a body, while weight is the force by which the body is attracted.
Weight is never constant while mass is. So we can have weight zero but with some mass. This will happen when an object is at the centre of earth, as g=0 at centre of earth , so weight will be 0 while mass will always be constant everywhere
Answer:
V=14.9 m/s
Explanation:
In order to solve this problem, we are going to use the formulas of parabolic motion.
The velocity X-component of the ball is given by:

The motion on the X axis is a constant velocity motion so:

The whole trajectory of the ball takes 1.48 seconds
We know that:

Knowing the X and Y components of the velocity, we can calculate its magnitude by:

Displacement only contain the length of movement and the direction of that movement
So you can pretty much disregard the speed.
30 to the west than 40 to the east
The displacement will be 10 km to the east
hope this helps
I think some of the given is wrong, 10 ms-1, think it is only 10 s-1 which represents the frequency of the wave, and can be use to solve for the wavelength of the sound wave given
wavelength = wave speed / frequency
wavelength = 1500 m/s / 10 s-1
wavelength = 150 m ( 100 cm / 1 m ) = 15000 cm
