Your hypothesis can be that the group with calculators would finish faster than the group without calculators.
Explanation:
To convert from scientific notation to decimal, move the decimal point 5 places to the left.
5.93×10⁻⁵ = 0.0000593
49 J is the total kinetic energy. If a bowling ball of mass 7.3 kg and radius 9.6 cm rolls without slipping down a lane at 3.1 m/s. Kinetic energy is the energy an bowling ball has because of its motion.
Given: m = 7.3 Kg ; r = 9.4 cm = 0.094 m ; v = 3.1 m
Now total kinetic energy in this case is given by KE = Kinetic energy due to rotation + Kinetic energy due to translation
i,e KE = 1/2*m*v2 + 1/2*I*ω2 where I is the moment of inertia of the bowling ball about it's center and ω is the angular velocity
Now for pure rotation (without slipping) v = rω
also for the ball (solid sphere) I = 2/5*m*r2
Hence our kinetic energy becomes
KE = 1/2*m*v2 + 1/5*m*v2 = 7/10*m*v2
so KE = 0.7*7.3*(3.1)2 = 49.10 J = 49 J

Answer:
Time period, T = 403.78 years
Explanation:
It is given that,
Orbital distance, 
Mass of the Earth, 
Mass of the planet, 
Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.



or
T = 403.78 years
So, the orbital period of this planet is 404 years. Hence, this is the required solution.
The answer would be East. Negative particle. if that reads west then the opposite is east.
