Answer:
Height of the balloon is 6.923 miles or 11141.46m
Explanation:
We form two triangles with a common vertex so the relation of the angles is and the position both are measuring
The second triangle have the mileposts on the road that is a mile more so:
Now resolve the both equation to know the opposite side that is the height of the hot air balloon
Height=6.923miles
Leigth can be find also
The measure can be express in meters so
Answer:
Because it kills people. I have had 6 relatives who have died from it in the past 2 years. It's horrible.
Explanation:
If you're wondering what causes cancer, it is rapid and uncontrollable cell regeneration. The majority of cancers result from random mutations arising during DNA replication in the normal stem cells required during development and tissue maintenance.
Answer:
100 g
Explanation:
Let the mass of density 1.2 g/cm³ be x gram and let the mass of density 1.8 g/cm³ be y gram
Applying
Density (D) = mass(m)/Volume (V)
Volume (V) = mass(m)/Density(D)
V = m/D........................... Equation 1
From the question,
x+y = 400...................... Equation 1
Volume of the liquidis
V = 400/1.6 = 250 cm³
(x/1.2)+(y/1.8) = 250
(1.8x/1.2)+y = 450............... Equation 1
Solving both equation simultaneously,
Subtract equation 1 from equation 2
x-(1.8x/1.2)+(y-y) = 400-450
x-1.5x = -50
-0.5x = -50
x = -50/-0.5
x = 100 g.
Hence the mass of the liquid of density 1.2 g/cm³ is 100 g
Missing part of the text:
"Two masses, m1 = 2.12 kg and m2 = 9.01 kg are on a horizontal frictionless surface and they are connected together with a rope as shown in the figure."
and missing figure (see attachment)
Solution:
We can write Newton's second law for the whole system m1-m2 and for m2 only (2 equations). Only one force (F) acts on the m1-m2 system, while if we consider m2 only we have two forces acting on it: F and T (tension), in the opposite direction. So, the two equations are
where a is the acceleration of the system.
From the first equation we get
and substituting it inside the second equation, we get
re-arranging, we get
Using
,
, and using the maximum value of T that is allowed not to break the rope (T=55 N), we can find the maximum allowed value for F:
