Answer:
Energy will be equal to 
Frequency will be equal to 
Explanation:
We have given frequency of the radar f = 10 GHz 
Speed of light 
Plank's constant 
So energy 
,here h is plank's constant and 
is frequency
So energy 
In second case we have given wavelength = 25 cm = 0.25 m
Wavelength is equal to 
So 
So frequency will be equal to
Answer:
0.41s
8.01m/s
Explanation:
Using the formula; v = u + at
Where;
u = initial velocity (m/s)
v = final velocity (m/s)
t = time (s)
a = acceleration (m/s²)
According to the provided information, u = 4m/s, s = 8m,
V = u + at
4 = 0 + 9.8t
4 = 9.8t
t = 0.41s
b) v = u + at
v = 4 + 9.8(0.41)
v = 4 + 4.018
v = 8.018m/s
Answer:
Actual Mechanical Advantage
Explanation:
AMA=mg/F(applied)
I do not understand what your saying could u plz be more specific?
No. It is D. Science is actually testable. That is the purpose of the scientific method: to TEST a theory. For something to be considered science, you must be able to observe, ask questions, develop questions, and test them. Thefore, it is a process. Lastly, yes. Science is a body of knowledge. It's a subject field that covers many things and numerous sub areas.
