6. An elevator takes 33k) of energy to lift a group of people up 6 m. What is the total mass of
Xelga [282]

Answer:

350 Kg

Explanation:

We use the Work Formula:

W = Force . Distance

33.000 Joules = Force . 6

Force = 5500 Newtons

Force = Mass . Acceleration

5500 = Mass . 10

Mass = 550

550 - 200 = 350 Kg

What are the starting materials for nuclear fission
aliina [53]
In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235. 
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.

What is the potential energy of two charges of +4.6 μC and +1.0 μC that are separated by a distance of 10.0 cm?
Artist 52 [7]

Answer:

U = 0.413 J

Explanation:

the potential energy between two charges q1 and q2 is given by the following formula:

U=k\frac{q_1q_2}{r}    (1)

k: Coulomb's constant = 8.98*10^9 NM^2/C^2

q1: first charge = 4.6 μC = 4.6*10^-6 C

q2: second charge = 1.0 μC*10^-6 C

r: distance between charges = 10.0 cm = 0.10 m

You replace the values of all variables in the equation (1):

U=(8.98*10^9Nm^2/C^2)\frac{(4.6*10^{-6}C)(1.0*10^{-6}C)}{0.10m}=0.413\ J

Hence, the energy between charges is 0.413 J
