Answer:
Explanation:
Amount of gold deposited = 0.5 g
Gold's molar mass = 197 g/mol
Time duration, t = 6 hours
= 6 × 3600
= 12600 s
Calculation of moles: mass/molar mass
= 0.5/197
= 0.00254 mole
Assuming
Au --> Au+ + e-
Faraday's constant = 9.65 x 10^4 C mol-1
Charge, Q = 96500 × 0.00254
= 244.924 C
Relation: Q = I × t
Thus, I = 244.924/12600
= 0.011 A
= 11.34 mA.
Answer:
The mass will be 4.437 kg
Explanation:
The force constant k is given as 7 N/m
The time period of oscillation T is 5 sec
Thus, angular frequency 
It is known that angular frequency is computed via
Squaring both sides gives us
The mass equals 4.437 kg
<span>(a) 0.0676 l
(b) 67.6 cc
We are given that 5.00 L of blood circulates through the heart every minute, with the heart beating 74.0 times per minute. Therefore, for each heartbeat, 5.00 L / 74.0 = 0.067567568 L of blood passes through. Rounding to three significant figures, the result is 0.0676 l. To convert liters to cubic centimeters, multiplying by 1000 leads to 67.6 cc of blood per heartbeat.</span>
Answer:
The book is titled Solid State or Condensed Matter
Explanation:
Response:
Clarification:
Impulse is equal to change in momentum
mv - mu, where v and u represent the final and initial velocities during the surface impact
For the downward motion of the baseball
v² = u² + 2gh₁
= 2 x 9.8 x 2.25
v = 6.64 m / s
This becomes the initial velocity upon impact.
For the upward movement
v² = u² - 2gh₂
u² = 2 x 9.8 x 1.38
u = 5.2 m / s
This becomes the final velocity post-impact
change in momentum is
m ( final velocity - initial velocity )
.49 ( 5.2 - 6.64 )
=.7056 N.s.
Impulse exerted by the floor in the upward direction is
=.7056 N.s
