Answer:
the volume of the cone is 
Explanation:
The computation of the volume of the cone is shown below:
As we know that
The Volume of the cone is
r denotes the radius
And, h denotes the height
So,
Hence, the volume of the cone is
Momentum = (mass) x (speed)
(Speed = magnitude of velocity)
36,000 kg-km/hr = (1,500 kg) x (speed)
Divide each side by (1,500 kg) :
Speed = (36,000 kg-km/hr) / (1,500 kg)
Speed = (36,000 / 1,500) kg-km / hr-kg
Speed = 24 km/hr
Answer:
B is the answer because it's the closest to the sun, so it has a smaller path.
Answer:
Time needed: 2.5 s
Distance covered: 31.3 m
Explanation:
I'll start with the distance covered while decelerating. Since you know that the initial speed of the car is 15.0 m/s, and that its final speed must by 10.0 m/s, you can use the known acceleration to determine the distance covered by
v2f=v2i−2⋅a⋅d
Isolate d on one side of the equation and solve by plugging your values
d=v2i−v2f2a
d=(15.02−10.02)m2s−22⋅2.0ms−2
d=31.3 m
To get the time needed to reach this speed, i.e. 10.0 m/s, you can use the following equation
vf=vi−a⋅t, which will get you
t=vi−vfa
t=(15.0−10.0)ms2.0ms2=2.5 s
Answer:
68 ohm
Explanation:
Output Voltage, Vout = 5 V
Forward voltage, Vf = 3.65 V
Forward current, If = 20 mA = 0.02 A
Let the resistance is R.
Use the formula
R = 67.5 ohm
R = 68 ohm ( approx.)
