Answer:
1.F = 256 N
2.a = 8 m/s/s
By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.
F = ma
256 N = m * 8 m/s/s
m = 256 N/8 m/s/s
m = 32 Kg
Answer:
The vertical component of the velocity is about 16 m/s.
Explanation:
The vertical component is the magnitude of the velocity reduced by the sinus of the angle 53 degrees. So
Answer: So, our current when our switch is open is going to be equal to the voltage across the resistors, and that's going to be our 12 volts, 12 volts, divided by the equivalent resistance of these resistors. When the switch is open, essentially, we just have R1 and R2 in series, and so this is just gonna be R1+R2.
Hope this helps......... Stay safe and have a Merry Christmas!!!!!! :D

Answer:
29.2 m/s
Explanation:
The escape velocity of an object from the surface of a planet is given by:
where
G is the gravitational constant
M is the mass of the planet
r is the radius of the planet
In this problem, we have
is the mass of the Death Star
is its radius
Substituting into the equation, we find
