Answer:
d = 0.0625 m
Step-by-step explanation:
The velocity of an object dropped from a tall building is given by :
Where
d is the distance in feet
We need to find the distance when the velocity is 32 ft/s
Rearranging for d,
Put v = 32 ft/s
So, the required distance is 0.0625 m.
Answer:
The value of x in centimeters is 22.5 cm
Step-by-step explanation:
The corresponding sides of the similar triangles are proportion which means have equal ratios
∵ Δ ABC is similar to Δ FGH
∵ AB and FG are corresponding sides
∵ BC and GH are corresponding sides
∵ AC and FH are corresponding sides
→ That means the ratios between them are equal
∴ =
=
∵ AB = 6 cm and FG = 15 cm
∵ BC = 5 cm and GH = 12.5 cm
∵ AC = 9 cm and FH = x
→ Substitute them in the rule above to find x
∴ =
=
→ By using cross multiplication with the 1st and 3rd ratios
∵ 6 × x = 15 × 9
∴ 6x = 135
→ Divide both sides by 6 to find x
∵ =
∴ x = 22.5 cm
∴ The value of x in centimeters is 22.5 cm
Answer:
The length of pendulum is 55.853cm
Step-by-step explanation:
We are given
the original pendulum completed one swing every 1.5 seconds
so, T=1.5 sec
now, we can use time period formula
l is the length of pendulum
g is acceleration due to gravity
now, we can plug values
and then we can solve for l
In cm
