Answer:
a =45 m/s2
t = 2 seconds
Explanation:
Hi, to answer this question we have to apply the next formula:
v^2 = u^2 +2 a d
Where:
v = final velocity = 90 m/s
u = initial velocity = 0 m/s (shots from rest)
a = acceleration (m/s2)
d = distance = 90m
90^2 = 0^2 + 2a(90)
Solving for a:
8,100= 180 a
8,100/180 = a
a = 45 m/s^2
For time:
v = u + at
90 = 0 + 45t
90/45=t
t =2 seconds
Answer: the nucleus
Explanation: The central nucleus is the oldest and most densely packed part of the milky way.
Freezing (liquid to solid)
Deposition (gas to solid)
Condensation (gas to liquid)
All three of these state changes are a result of a energy loss. When considering energy loss it is best to think of situations where temperature has dropped. Less energy in the system results in less energy the substance is exposed to or has available.
Answer:
864 KN
Explanation:
(Absolute pressure) = (Atmospheric pressure) + (Gauge Pressure)
Atmospheric pressure = 95 KPa = 95000 Pa
Gauge Pressure = ρgh
ρ = density of the fluid = 1000 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = depth below the fluid level that the object is at = 5 m
Gauge Pressure = 1000 × 9.8 × 5 = 49000 Pa
Absolute pressure = 95000 + 49000 = 144000 Pa.
Pressure = (Hydrostatic force)/(Area perpendicular to the force)
Hydrostatic force = (Pressure) × (Area perpendicular to the force)
Area perpendicular to the force = 2 × 3 = 6 m²
Hydrostatic force on the top of the plate = 144000 × 6 = 864000 N = 864 KN
Hope this Helps!!!
Exosphere is the answer . I have done this lesson in my physics class it's exosphere.
