Answer:
1980 kg m/s due south
8.2 m/s2 north-west
Explanation:
In order a quantity to be a vector, it should both has a magnitude and direction.
27 J/s --> Only magnitude. (Power)
1980 kg m/s due south --> Both magnitude and direction. (Momentum)
8.2 m/s2 north-west --> Both magnitude and direction. (Acceleration)
3.2 mi straight up --> Direction is not clear. (Position)
2.9 m/s2 --> Only magnitude. (Magnitude of acceleration)
293 K --> Only magnitude. (Temperature)
200 s --> Only magnitude. (Time)
Primary waves are faster than Secondary waves
Answer:
d = 265 ft
Therefore, an object fall 265 ft in the first ten seconds after being dropped
Explanation:
This scenario can be represented by an arithmetic progression AP.
nth term = a + nd
Where a is the first term given as 2.63 ft.
d is the common difference and is given as 5.3ft.
n is the particular second/time.
To calculate how far the object would fall in the first 10 seconds, we can derive it using the sum of an AP.
d = nth sum = (n/2)(2a+(n-1)d)
Where n = 10 seconds
a = 2.65 ft
d = 5.3 ft
Substituting the values we have;
d = (10/2)(2×2.65 + (10-1)5.3)
d = 265 ft
Therefore, an object fall 265 ft in the first ten seconds after being dropped
The slope of distance/time is velocity. (Actually speed.) . . . The slope of velocity (actually speed)/time is acceleration. ... The slope of acceleration/time has a name, but this website misundersttod it and would not let me post it. Nobody ever talks about it.
Answer:
D
Explanation:
The atmosphere is made up of constituents not chemically combined unlike the rest of the options...
The atmosphere is made up of O2, N2, etc. and they are not chemically combined, hence the atmosphere is a mixture
