Answer:
25 m/s
Explanation:
F=ma
15 N =(3 kg)a
a = 5 m/s^2
change in velocity = a*t = (5 m/s^2) * (5 secs) = 25 m/s
Answer:
(C) Independent variable
Explanation:
Independent is the variable used by the experimenter to vary a condition of interest in the experiment (temperature in this case). This measure is varied over a sensible range to induce changes in other aspects (dependent variables; level of aggression in this case) which are measured during the experiment.
Answer:
a
b
c
Explanation:
From the question we are told that
The Young modulus is
The length is
The area is
Generally the force acting on the tibia is mathematically represented as
derived from young modulus equation
Now this force can also be mathematically represented as
So
substituting values
Since the tibia support half the weight then the force experienced by the tibia is
From the above equation the extension (compression) is mathematically represented as
substituting values
From the above equation the maximum force is
Answer:
0.124 miles
Explanation:
Since the radius of the atom R = 10000r where r = radius of nucleus. Now, if r = 2.0 cm = 0.02 m,
R = 10000r
= 10000 × 0.02 m
= 200 m
We know that 1 mile = 1609 m.
So the radius of the atom in miles is R = 200 m × 1 mile/ 1609 m = 0.124 miles
So, the radius of the atom in miles is 0.124 miles
