ddd [48]

This depends on how big the bag is. Most commonly, the bag weighs 2 kg to 10 kg or more. With this range of weight, Siobhan should use a balance to measure the mass of the flour and record the mass in kilograms. Thus, the answer is the first choice

A youngster throws a rock from a bridge into the river 50 m below. The rock has a speed of 15 m/s when it leaves the youngster’s

butalik [34]

Assuming that the stone is thrown vertically... let's say it's a 1 kg stone.It doesn't matter if it's thrown upwards or downwards as (assuming no air friction) it will pass the original throwing point with the same downwards velocity as it had upwards, 3 seconds previously. So it starts with 1/2 m v^2 = 0.5 * 1 * 15^2 = 112.5 J of keThen k.e. gained = gpe lostk.e. gained = m g h = 1 * 10 * 50 = 500 J of Ke gainedso the final (total) ke is 612.5 J which = 1/2 m v^2 = 0.5 v^2 here
so 0.5 v^2 = 612.5so v^2 = 1225so v = 35 m/s

Answer:

1. The Speed is 390

2. The Frequency is 425 Hz

3. The Wavelength is 1.3

1. To find the speed of a wave you have to do the formula of speed.

Speed = Wavelength x Wave Frequency.

Speed = 1.5 * 260
