Answer:
a) 104
b) 106
c) 884 mA
Explanation:
The ratio of the transformer is given by:
We need to know the current in the primary in order to obtain the power applied.
The current rating of the fuse is the current on the primary, 884mA as we calculated before in order to obtain the power.
Water vapor and carbon dioxide.
The BUS will have the highest kinetic energy, while the BICYCLE will have the lowest kinetic energy.
This is because if an object has a greater mass, the kinetic energy of the object also increases. Kinetic energy depends on mass and velocity (KE=1/2*m*v^2) and since the velocity of these vehicles are the same, the mass is the only difference
Answer:
e = 50.27 give / s
Explanation:
The expression for simple harmonic motion is
x = A cos (wt + Ф)
in this case they give us the amplitude A = 3.9 cm and frequency f = 8.0 Hz
The angular and linФear variables are related
e = 2π d
e = 2π 8
e = 50.27 give / s
let's look for the constant fi
so let's find the time to have the maximum displacement
v = dx / dt
v = -A w sin (wt +Ф)
for the point of maximum displacement the speed is I think
0 = - sin (0 + Ф)
therefore fi = 0
Let's put together the equation of motion
x = 0.039 sin (50.27 t)
v = 0.039 50.27 sin (50.27 3)
v = 1.96 50 0.01355
v = 0.0266 m / s
B is the answer because a solid would not be able to hold its shape if it was able to move around
