What is unusual about the results of mass determinations of clusters of galaxies?

Physics

Galaxy clusters are the most recent, gravitationally bound products of the hierarchical mass accretion over cosmological scales. There is much more mass than can be accounted for by the visible galaxies.

The mass measurement of galaxy clusters is an important tool for the determination of cosmological parameters describing the matter and energy content of the Universe. However, the standard methods rely on various assumptions about the shape or the level of equilibrium of the cluster.

A rotating water pump works by taking water in at one side of a rotating wheel, and expelling it from the other side. If a pump
Xelga [282]

Answer:

Explanation:

initial angular velocity, ωo = 0 rad/s

angular acceleration, α = 30.5 rad/s²

time, t = 9 s

radius, r = 0.120 m

let the velocity is v after time 9 s.

Use first equation of motion for rotational motion

ω = ωo + αt

ω = 0 + 30.5 x 9

ω = 274.5 rad/s

v = rω

v = 0.120 x 274.5

v = 32.94 m/s

How would you determine the volume of an irregularly shaped object such as a paper clip?
zheka24 [161]

Explanation:

Take a measuring cylinder and fill it with a certain amount of water. Measure this amount of water.

Place the paper clip in the filled measuring cylinder. You will notice that the water level has gone up. When we place the paper clip in the cylinder the volume of the paper clip gets added to the volume that was present in the cylinder.

The volume of the paper clip will be the final volume of water with the paper clip - The initial volume of water without the paper clip.

Any irregularly shaped object's volume can be determined by this method.

The load across a 12 V battery consists of a series combination of three resistors 34 Ω, 42Ω, and 30Ω. What is the total resista
stira [4]

Answer:

The total resistance is 106 Ω and the current in the circuit is 0.11 A.

Explanation:

Given that,

Voltage of the battery, V = 12 V

Resistors 34 Ω, 42Ω, and 30Ω are connected in series.

The total resistance is given by :}

R = 34 + 42 +30

= 106Ω

Let I is the total current in the circuit. Using ohm's law to find it such that,

I=\dfrac{V}{R}\\\\I=\dfrac{12}{106}\\\\I=0.11\ A

Hence, the total resistance is 106 Ω and the current in the circuit is 0.11 A.
