Answer: 510 m/s
Explanation: specific gravity of steam is 18/29 = 0.620
It is the ratio of the density of steam over density of water
400m3/s of steam =
400m3ms * 0.620 of water
= 248m3/s of water
Total flow rate Q = 248 + 7 = 255m3/s
Using Q = AV
Where A is area and V is velocity
V = Q/A
V = 255/0.5 = 510m/s
You know how speed is how fast distance changes ?
Well, velocity is speed PLUS the direction of the motion,
and acceleration is how fast velocity changes.
An electromagnet is a device that sends electricity through a coil of wire to produce a magnetic field. This leads to a magnet that can be controlled - turned on and off with the flip of a switch, or increased or decreased in strength. The coils are often wrapped around a regular magnet to make it stronger.
Answer:
a and c are both correct
Explanation:
The Greek Philosophers had to reject many existing explanations (mostly from the babylonians and the egyptians) because of possible religion bias. <u>They resorted to logic and reason to provide understanding for the world around them</u>. The first set of Greek Philosophers were the Milesian thinkers; <u>whom aside from logic and reason also placed value on Observation in understanding the world</u>.
There are generally no evidence to support the use of experiment to support the claims of the Greek philosophers
Answer:
4 m/s²
Explanation:
Given:
Δx = 60 m
v₀ = 2.0 m/s
v = 22 m/s
Find: a
v² = v₀² + 2aΔx
(22 m/s)² = (2.0 m/s)² + 2a (60 m)
a = 4 m/s²
