Answer:
F = - K X force constant for spring
a = F / m maximum acceleration
F = 4.5 kg * 26 m/s^2 = 117 Newtons
(A) K = 117 N / .038 m = 3079 N/m
ω = (K/M)^1/2 = (117/5)^1/2 = 4.84 / sec
(B) f = ω / 2 pi = 4.84 / 6.28 = .77 /sec
(C) P = 1 / f = 1/.77 = 1.30 sec
4 Hz is the difference between 510 and the unknown.
<span>Therefore the unknown is either 514 or 506. </span>
<span>If 505 and 506 were struck together, the diff would be 1 Hz </span>
<span>If 505 and 514 were struck toghether, the diff would be 9 Hz which would be difficult to count accurately, </span>
<span>Therefore the unknown is 514</span>
Complete question is;
Jason works for a moving company. A 75 kg wooden crate is sitting on the wooden ramp of his truck; the ramp is angled at 11°.
What is the magnitude of the force, directed parallel to the ramp, that he needs to exert on the crate to get it to start moving UP the ramp?
Answer:
F = 501.5 N
Explanation:
We are given;
Mass of wooden crate; m = 75 kg
Angle of ramp; θ = 11°
Now, for the wooden crate to slide upwards, it means that the force of friction would be acting in an opposite to the slide along the inclined plane. Thus, the force will be given by;
F = mgsin θ + μmg cos θ
From online values, coefficient of friction between wooden surfaces is μ = 0.5
Thus;
F = (75 × 9.81 × sin 11) + (0.5 × 75 × 9.81 × cos 11)
F = 501.5 N
185 newtons because (W=Fd so W/d=F)296/1.6=185
Answer:
Corpus callosum
Explanation:
The corpus callosum is the tissue in the brain that helps in the connection between the right and left cerebral hemisphere.
The corpus callosum consists of about 200 million axons of thick nerve cells which helps in combining sensory and cognitive signals between the two hemispheres.
Almost everyone is born with this tissue because an absence of deficiency of it results in serious neurological problems such as difficulty in learning and other cognitive related diseases.
