Answer:
k = 22.05 N/m
Explanation:
The potential energy of the mass is converted into potential energy of the spring.
Given:
mass m = 0.27 kg
gravitational constant g = 9.8 m/s²
distance falling/ stretching of spring h = 0.24 m
Solving for k:
Answer:
707 m/s
Explanation:
Since the root mean temperature is directly proportional to the root mean square velocity.
We have
V1/V2 =√T1/T2
V1= root mean square velocity of nitrogen at 300K
V2= root mean square velocity of nitrogen at 600K
Thus;
517/V2 = √300/600
517/V2 = 0.707
V2 = 500/0.707
V2= 707 m/s
Answer:
the current flowing through the filament would be 5 amperes.
Explanation:
we know that according to OHMS law
V=I×R
where i is the current and R is the resistance and V is the voltage
applying the values in the formula
We get I = 5 A.
Answer:
the statement that best compares potential and kinetic energy would be only kinetic energy increases when velocity of an object increases
