Answer:
1.08 m/s
Explanation:
This can be solved with two steps, first we need to find the time taken to fall 9.5 m, then we can divide the horizontal distance covered with time taken to calculate the velocity.
Time taken to fall 9.5 m
vertical acceleration = a = 9.8 m/s^2.
vertical velocity = 0, (since there is only horizontal component for velocity,
)
distance traveled s = 9.5 m.
Substituting these values in the equation
⇒ t= 1.392 sec
Velocity needed
We know the time taken (1.392 s) to travel 1.5 m,
So velocity = 1.5 m / 1.392 s = 1.08 m/s
hence velocity of the diver must be at least 1.08 m/s
This method is known as linear perspective.
When using linear perspective, artists use a set of drawn or imaginary lines which are made to converge at the horizon of the image. These lines change the viewer's perspective by providing a point through which the relative size, shape and position of objects is determined. This technique creates the illusion of depth.
Time is being measured in days here so if you want to calculate the rate of increase after one day, substitute 1 for t in your rate equation:
dB/dt = 0.677598 cos(1.232(1))
dB/dt = 0.22
Answer:
85 K
Explanation:
T₀ = initial temperature of the gas = 77 K
T = final temperature of the gas = ?
n = number of moles of monoatomic gas = 1.00 mol
R = universal gas constant = 8.314
c = heat capacity at constant volume = (1.5) R = (1.5) (8.314) = 12.5
Q = Amount of heat absorbed = 100 J
Amount of heat absorbed is given as
Q = n c (T - T₀)
100 = (1) (12.5) (T - 77)
T = 85 K
