There aren’t many but i would say one is that you’re brain isn’t as active as it was while you were working and also your not exercising as much as you were while in your old job (depends on your job)
Answer:
5.1 rad/s
Explanation:
Mechanical energy of the system is conserved since no external work is done on the sphere.
Substituting v = ωr and I = 2 m r^2/5, we get,
=>
=>
=>
=>
=>
=> = 5.1 rad/s
Explanation:
given that the raven flies south for
time= 10 sec
speed= 10km/s
we know that speed=distance/time
distance=speed*time
distance=10*100
distance=1000m
distance=1km
also flies
distance=0.5km = 500m
time= 50 sec
speed= distance/time
speed=500/50
speed= 10m/s
speed= 0.01km/s
The average speed of an object is defined as the distance traveled divided by the time elapsed.
average speed= (1000+500)/10+50
average speed= (1500)/60
average speed= 25m/s
average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s
Answer:
E = 4.78*10^6 N/C
Explanation:
In this case you have to take into account that both magnetic force and electric force must be equal
However, you have to know first what is the speed of the electron by using the expression for the kinetic energy (1keV=1000*1.6*10^{-19}J):
by replacing in the expression for the forces you have

Answer:
6.28 * 10⁴ m/s
Explanation:
Using the relation :
Given :
Radius, R = 10km
Period, T = 1.0 s
v = (2πR) / T
Where v = velocity of a point
R in meters ;
1km = 1000m = 10³m
10km = 10 * 10³m = 1 * 10^4 m
v = (2π*10^4m) / 1 s
v = 6.2831853 * 10⁴ m/s
v = 6.28 * 10⁴ m/s
