Peer review is subjecting the author's scholarly work and research to the scrutiny of other experts in the same field to check its validity and evaluate its suitability for publication.
A peer review helps the publisher decide whether a work should be accepted.
Answer:
Explanation:
All the rest of the information is extraneous. The only 2 things you have to know are
d = 20 km
t = 8 minutes = 8/60 hours = 0.13333333
So the speed is s = d/t
s = 20/0.1333333 = 150 km/hour
Note: you have not specified what units the speed is. I suppose you could answer 20/8 = 2.5 km/min
Answer:
Explanation:
Examples are;
Ultraviolet light from sun.
Heat from a stove burner.
X-ray from an x-ray machine.
Alpha particle emit from a radio active decay of uranium.
Sound waves from your stereo.
Microwave from micro oven.
ultraviolet light from a black light.
Gamma radiations from a supernova.
AND MANY MORE.
It should be C. If the object is denser than the fluid, it will sink. If it isn't, it will float
Answer:
v = 23.66 m/s
Explanation:
recall that one of the equations of motion may be expressed:
v² = u² + 2as,
Where
v = final velocity (we are asked to find this)
u = initial velocity = 0 m/s since we are told that it starts from rest
a = acceleration = 0.56m/s²
s = distance traveled = given as 500m
Simply substitute the known values into the equation:
v² = u² + 2as
v² = 0 + 2(0.56)(500)
v² = 560
v = √560
v = 23.66 m/s
