Answer:
1.056 x 10⁷ lb-ft
Explanation:
v = Speed of the bike = 20 mph
t = time of travel = 2 h
d = distance traveled by cyclist
Distance traveled by cyclist is given as
d = v t
d = (20) (2)
d = 40 miles
We know that, 1 mile = 5280 ft
d = 40 (5280) ft
d = 211200 ft
F = force applied by cyclist = 50 lb
W = work done by cyclist
Work done by cyclist is given as
W = F d
W = (50) (211200)
W = 1.056 x 10⁷ lb-ft
Helium’s state when the decompressed
helium atoms expand and float up, making the rubber balloon expand around them
and float with them is gas.
<span>Helium is a chemical element with symbol He and atomic number 2. It is a
colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in
the noble gas group in the periodic table. Its boiling point is the lowest
among all the elements.</span>
Answer:
<h2>13N</h2>
Explanation:
<em>Kindly see attached file for your reference</em>
Step one:
given data
the horizontal component of the force= 12N
the vertical component of the force= 5N
The dashed arrow represents the hypotenuse of the triangle, hence the resultant of the force system.
By implication of this, we will use the Pythagoras theorem to solve for the resultant force
Step two:

Answer: Got It!
<em>Explanation:</em> Guide A Starts From Rest With Pin P At The Lowest Point In The Circular Slot, And Accelerates Upward At A Constant Rate Until It Reaches A Speed Of 175 Mm/s At The ... In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw.
Answer:
Part a)

Part b)

Explanation:
Part a)
Electric field due to large sheet is given as







now the electric field is given as


Part b)
Now since the electric field is required at same distance on other side
so the field will remain same on other side of the plate
