As you climb a mountain, your ears "pop" because of the changes in
(a) In which direction does your eardrum move as you climb up?
inward
outward
eardrum does not move
Give your reasoning.
I think the eardrum moves outward because the further you go away from the earth's center the less pressure there is. The eardrum was at an equilibrium on the ground but because the external pressure is less the pressure from the inside pushes on the eardrum pushing it outward.atmospheric pressure.
(b) In which direction does your eardrum move as you climb down?
inward
outward
eardrum does not move
Give your reasoning.
Going down is almost the opposite of going up. The eardrum moves inward from its outward position because the closer you get to the earth's center the more pressure is exerted on the eardrum. The closer you get to the ground the eardrum begins to return to its equilibrium state, neither inward or outward.
I have also figured this one out as well. Thanks!
it is correct.
How much force is needed to accelerate a 50-kg rider and her 250-kg motorcycle at 5 m/s 2?
a.) 1000 N
b.) 125 N
c.) 500 N
d/) 1500 N
F = ma
total mass = 300kg
acceleration = 5
F = 300 x 5 = 1500N
How much force is needed to accelerate a 50-kg rider and her 250-kg motorcycle at 5 m/s2?
1500
How much force is needed to accelerate a 50-kg rider and her 250-kg motorcycle at 5 m/s2?
N
The force needed to accelerate a 50-kg rider and her 250-kg motorcycle at 5 m/s^2 is 1500N.
To find the force needed to accelerate the rider and motorcycle, we can use the equation F = ma, where F represents the force, m represents the total mass, and a represents the acceleration.
In this case, the total mass is the sum of the rider's mass (50 kg) and the motorcycle's mass (250 kg), which equals 300 kg. The acceleration is given as 5 m/s^2.
Now, we can plug in the values into the equation:
F = 300 kg * 5 m/s^2
F = 1500 N
Therefore, the correct answer is d) 1500 N.
