How do you calculate the power of an object without finding time? Given only mass, height and speed. Thanks :))

Well, first of all, an 'object' doesn't have power. Power is the rate at which work is done or energy is moved or transferred. An object can have energy, and can carry energy from place to place, but you wouldn't ever say that the object 'has' power.

In order to calculate power, you need something like force, distance and time, or work and time, or energy and time. There's really no such thing as "the power of an object".

The only other remark I can offer is that if you do have mass, height, and a speed given, then you actually do have 'time'. That speed that you have is distance divided by time. So time is actually buried there in the data that you have.

Define Nuclear Physics ?

murzikaleks [220]

Answer:

Definition. Nuclear physics is the study of the protons and neutrons at the centre of an atom and the interactions that hold them together in a space just a few femtometres (10-15 metres) across. Example nuclear reactions include radioactive decay, fission, the break-up of a nucleus, and fusion, the merging of nuclei.

With certain exceptions, Class E airspace extends upward from either 700 feet or 1,200 feet AGL to, but does not include,A) 14,5

DedPeter [7]

Answer:

B) 18,000 feet MSL

Explanation:

There are three-dimensional parts in the navigation airspace in the world. The class E airspace is mostly used in the regions with coastal areas that are relatively populated. If we consider certain forms of exceptions, the class E airspace can move in the upward direction to few feet (i.e. 1200 ft). However, this doesn't include 18,000 feet MSL.

The voltage across a membrane forming a cell wall is 74.0 mV and the membrane is 9.20 nm thick. What is the electric field stren

Sindrei [870]

Answer:

7.60× 10^6 V/m

Explanation:

electric field strength can be determined as ratio of potential drop and distance, I.e

E=V/d

Where E= electric field

V= potential drop= 74.0 mV= 0.07 V

d= distance= 9.20 nm = 9.2×10^-9 m

Substitute the values

E= 0.07/ 9.2×10^-9

= 7.60× 10^6 V/m
