Explanation:
mass of copper block = 0.3 kg at 77 K or -196 °C
Let mass of water taken be m ( maximum) , in this case we will have mixture of water and copper block at 0°C finally.
Heat gained by copper block
= msΔt
.3 x 196 x 385 J
heat lost by water to lower its temp fro 50°C to 0°C
= m x 4186 x 50
Heat lost = heat gained
m x 4186 x 50 = .3 x 196 x 385
m = 108.16 gm
Let mass of water taken be m ( minimum ) , in this case we will have mixture of ice and copper block at 0°C finally.
heat lost by water to lower its temp fro 50°C to 0°C
= m x 4186 x 50
heat lost by water to lower its temp from 0°C to 0°C ice
= m x latent heat of fusion
m x 3.35 x 10⁵
Total heat lost
= m x 3.35 x 10⁵ + m x 4186 x 50
= 544300 m
Heat gained by copper block
= msΔt
.3 x 196 x 385 J
Heat lost = heat gained
544300 m = .3 x 196 x 385 J
m = 41.6 gm
Answer:
hurricanes are the most awesome Violet storms on the earth people call the storms by other names such as typhoon or cyclone depending on where the car whatever they are called topical cologne all from the same way
Explanation:
so technically hurricanes are the most Violet storms
The mass because u can look at this formula
F = G(m1 - m2/ d squared) - Do u see volume in this equation?
By Newton's second law,
<em>n</em> + (-<em>w</em>) = 0
<em>p</em> + (-<em>f</em> ) = (20 kg) (2 m/s²)
where <em>n</em> is the magnitude of the normal force, <em>w</em> is the weight of the box, <em>p</em> is the magnitude of the applied force (<em>p</em> for <u>p</u>ush or <u>p</u>ull), and <em>f</em> is the magnitude of the friction force.
Calculate the weight of the box:
<em>w</em> = (20 kg) (9.80 m/s²) = 196 N
Then
<em>n</em> = <em>w</em> = 196 N
and
<em>f</em> = <em>µ</em> <em>n</em> = 0.5 (196 N) = 98 N
Now solve for <em>p</em> :
<em>p</em> - 98 N = 40 N
<em>p</em> = 138 N
Answer:
d) business intelligence
Explanation:
Business intelligence refers to applications and technologies that are used to gather, provide access to, and analyze data and information to support decision-making efforts. Business Intelligence uses technologies for the data analysis of business information to make strategic decision for enterprises. Common functions of business intelligence technologies include reporting, online analytical processing, analytics, data mining, process mining, complex event processing, business performance management, benchmarking, text mining, predictive analytics and prescriptive analytics.
