7.12
7.3
7.28
Please help will be marked most brainlist !!
Zooming I. On the image the red line is just short of the 3rd line past the 7 so it is not 7.3 but just a little under.
Answer: 7.28
Can someone tell me which is which on what i put i dont know what i should put
Round 0.010229 to four sig figs
It would be 0.01023.
0.010229 has 5 sig. fig.'s (leading zeros do not count)
So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.

II.ampere
III.mole
IV.all of these
Answer:
all of these very easy questions
The elevators in the John Hancock building in Chicago move 783 ft in 33 s. What is this speed in miles per hour?
Answer:
16.18 mph
Explanation:
the speed of elevators =
(783×3600)/(33×5280) =
2,818,800/174,240 = 16.18 mph

How can radio waves & microwaves communicate over similar distances?
what is the density of a 75 g block of wood measuring 12 cm x 8cm x 9cm
Answer:
density is equal to mass divided by volume (m/v)
volume: 12×8×9=864cm³
75÷864=0.09
Answer: 0.09g/cm³
what is pulley? How does it help in lifting weight?
Hey there!
A pulley is a "system" that has a rope attached to carry heavy materials off the ground. Once you pull the rope, the heavy item will be carried.
Hope this helps!
Have a great day!
the density of the metal is 8.9g/cm³.what does it mean. What is the importance of the value
Density of the metal is 8.9g/cm^3
It means per 1cm^3 Volume there is 8.9g of Mass occupied .Density:-
[tex]\boxed{\sf Density=\dfrac{Mass}{Volume}}[/tex]
SI unit:-
SI unit of density is kg/m^3
CGS unitCGS unit of density is g/cm^3
a hot metal block is placed into 50g of water in an insulated container the water increases in temperature from 20c to 32c the specific heat capacity of water is 4200j/kgk calculate the quantity of heat energy supplied to the water from the metal
Answer:
25,000 joules
given the formula
Q=Mc(final temperature - initial temperature)
M=50 grams convert to kilogram 0.5
c= 4200 j/kg/k
final temperature=32c
initial temperature=20c

Which is the cause of the suns magnetic properties ?
A) upward movement or super heated gases in the convection zone
B) uneven churning of plasma
C) rapid spinning of metals in the core
D) uniform clockwise rotation of charger particles
Answer:
Q:
What characteristic is shared by sunspots, solar flares, and coronal mass ejections? Select the two correct responses.
A:
They tend to occur during active periods of the solar cycle. & They are caused by outward fluctuations of the sun's magnetic field.
Q:Drag each item to the correct location.
A: sunspot: cooler area on suns surface where the magnettic field emerges
solar flare: intense burst of radiation coming from the rapid release of magnetic energy
coronal mass ejection: large bubble of plasma from the rapid release of magnetic energy
Q: Which is the cause of the sun's magnetic properties?
A: uneven churning of plasma
Explanation:
took quick check
good luck yall
The uneven churning of plasma is the cause of the sun's magnetic properties, therefore the correct answer is option B.
What is a magnetic field?A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted.
For a simple bar magnet, N-pole and S-pole are the points on a magnet that have the strongest magnetic field. The magnetic field originates from the north pole and terminates in the south pole of a magnet.
The positively charged ions and negatively charged electrons that make up the plasma of the Sun move around a lot due to its high temperatures. Multiple intricate magnetic fields that twist and turn are produced by the moving plasma. A magnetic field is produced by the extremely hot plasma that escapes from the Sun as the solar wind.
Thus, The sun's magnetic properties are caused by uneven plasma churning, so option B is the correct answer.
