Answer:
A ramp
Explanation:
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.
Answer:
d) 14Ω
Explanation:
series resistors add so therefore 2+4+8=14
So you inherit genetic characteristics from your parents like hair color and eye color and skin tone. But environmental characteristics are like your taste in music and your favorite color. Stuff like that.
Answer:
FT = 103.15 N and T = 1.75 s
Explanation:
There are 3 forces at play here: gravity acting in vertical direction, tension from the string that makes 18 degrees with the vertical, and centripetal force generated by the circular motion which is horizontal.
Since the bob is moving at the constant speed, according to Newton 's 1st law the net force is 0. To find the tension force that makes a fixed angle of 18 degrees with the vertical, we can calculate that tension in the vertical direction and balance it with gravity force. Let g = 9.81m/s2
To calculate the centripetal force in the horizontal direction, we can calculate tension in the horizontal direction and balance it with the centripetal force
The centripetal acceleration a is
The radius of circular motion is:
The angular speed is
The time it would take to sweep 1 period, or 2π rad is
Answer:
It depends on the potential energy it has ontop of the ramp. The marble has the same potential energy was the kinetic energy without changing the ramp incline or moving it. What kinetic energy shows is what potential energy made it to be, so we look at how the ramp is placed. If the ramp is a steep incline the kinetic energy will be fast. It depends on the weight of the marble too. If the marble is heavy the potential energy will slowly tansition to kinetic energy while a light marble will transition to kinetic energy fast. But marbles are light so there we have it. It basically goes from potential energy to kinetic energy to thermal energy to potential energy. Make me brainliest pls :)
