Answer:
v = 27.456 m/s
Explanation:
The support pressure needed of the water in the straw can be calculated by the formula
Given that,
P = r*g*h
= 1000*9.8*0.05 Pa.= 490 Pa
This pressure is compensated by 0.5*r*v^2 of the air,
Hence,
0.5*1.3*v^2 = 490
velocity of air blown into the straw =
v = 27.456 m/s
Answer:
Approximately
.
Explanation:
Assuming that there is no other force on this vehicle, the
force from the road would be the only force on this vehicle. The net force would then be equal to this
force. The size of the net force would be
.
Let
denote the mass of this vehicle and let
denote the net force on this vehicle.
By Newton's Second Law of motion, the acceleration of this vehicle would be proportional to the net force on this vehicle. In other words, the acceleration of this vehicle,
, would be:
.
For this vehicle,
whereas
. The acceleration of this vehicle would be:
.
Answer:It's how the color mixes together . Red and green both makes a dark color
Explanation:
I believe C is your answer (also, I am also using tht same exact program!)
Answer:

Explanation:
Given:
- mass of vehicle,

- radius of curvature,

- coefficient of friction,

<u>During the turn to prevent the skidding of the vehicle its centripetal force must be equal to the opposite balancing frictional force:</u>

where:
coefficient of friction
normal reaction force due to weight of the car
velocity of the car

is the maximum velocity at which the vehicle can turn without skidding.
