Frequency = 1/T
as the 5 is reduced, frequency is increase.
as 1 whole wave travels through a point in a lesser time now
Answer:
W₂= 10000 N
Explanation:
Pascal´s Principle can be applied in the hydraulic press:
If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:
Pressure is defined as the force (F) applied per unit area (A)
P=F/A (N/m²)
P1=P2
Equation (1)
Data
W₁ = weight sits on the small piston
F₁ = W₁= 500 N
A₁ = 2.0 cm²
A₂ = 40 cm²
Calculation of the weight (W₂) can the large piston support
We replace data in the equation (1)
F₂ = 10000 N
W₂= F₂= 10000 N
A liquid has a definite volume but takes the shape of whatever object it's in.

Answer:
Surface waves are the kind of waves that occur on the surface of the ocean. The reason behind their occurrence is the geological effects, usually in the form of winds in near geographical regions or in that region.
These waves reach the land when the geological winds give a push to the waves and they travel miles and finally hit the land. These waves range in sizes, for small sizes to the the size of tsunami.
Answer:
h = 384.4 m
t = 8.5 s
Explanation:
The firework will explode at the highest point. Because it would start to move downward at the highest point. Using 3rd equation of motion:
2ah = Vf² - Vi²
where,
a = acceleration due to gravity at that planet = -10.56 m/s²
h = maximum height = ?
Vf = Final velocity = 0 m/s (since, firework stops at highest point)
Vi = Initial Velocity = 90.1 m/s
Therefore,
2(-10.56 m/s²)(h) = (0 m/s)² - (90.1 m/s)²
<u>h = 384.4 m</u>
Now, we use 1st equation of motion:
Vf = Vi + at
0 m/s = 90.1 m/s + (-10.56 m/s²)(t)
<u>t = 8.5 s</u>
