Answer:
a) x = (0.0114 ± 0.0001) in
, b) the number of decks is 5
Explanation:
a) The thickness of the deck of cards (d) is measured and the thickness of a card (x) is calculated
x = d / 52
x = 0.590 / 52
x = 0.011346 in
Let's look for uncertainty
Δx = dx /dd Δd
Δx = 1/52 Δd
Δx = 1/52 0.005
Δx = 0.0001 in
The result of the calculation is
x = (0.0114 ± 0.0001) in
b) You want to reduce the error to Δx = 0.00002, the number of cards to be measured is
#_cards = n 52
The formula for thickness is
x = d / n 52
Uncertainty
Δx = 1 / n 52 Δd
n = 1/52 Δd / Δx
n = 1/52 0.005 / 0.00002
n = 4.8
Since the number of decks must be an integer the number of decks is 5
Answer:
what
Explanation:
Racket sports include tennis, badminton, squash or any other sport where you use rackets to hit a ball or shuttlecock to play. They can be played competitively or just for fun and are a great form of physical activity.
No, he should place the He atom and energy on the right, and the H atoms and the heat and energy on the left.
Answer:
Distance between Venus and Sun is 1.0864x10^11 m
Explanation:
Data
T1 (Total time taken by earth to rotate around sun)=365 days
T2 (Total time taken by venus to rotate around sun)=225 days
R1 (Radius b/w Sun and earth)=1.5x10^11m
R2(Distance between Venus and Sun)=?
Solution
Apply Kepler Law
(R2)^3/(R1)^3=(T1)^2/(T2)^2
(R2)^3/(1.5x10^11)^3=(225^2)/(365^2)
R2=1.0864x10^11m
The maximum height reached by the ball is 0.46m.
To find the answer, we have to know about the potential energy of a spring mass system.
<h3>How to find the maximum height reached by the ball?</h3>

- We have to find the maximum height reached by the ball.
- Thus, we have the expression for potential energy of a spring mass system and that of gravitational field as,


Thus, we can conclude that, the maximum height reached by the ball is 0.46m.
