Two objects allowed to move freely will accelerate toward each other
in response to the gravitational forces between them.
It doesn't matter whether they have equal masses or vastly different
masses ... each object accelerates toward the other one.
The less-massive object has greater acceleration, and the more-massive
object has smaller acceleration.
Yes. When you fall to the Earth, the Earth falls to you, but with less
acceleration because it has less mass than you have.
Answer:
132.64m/s
Explanation:
Averagevelocity= distance/time
From the question, the distance d = 825m
time t = 6.22 secs
Using the above formula
We have
average velocity = 825/6.22
= 132.64m/s
A) 1.05 N
The power dissipated in the circuit can be written as the product between the pulling force and the speed of the wire:
![P=Fv](https://tex.z-dn.net/?f=P%3DFv)
where
P = 4.20 W is the power
F is the magnitude of the pulling force
v = 4.0 m/s is the speed of the wire
Solving the equation for F, we find
![F=\frac{P}{v}=\frac{4.20 W}{4.0 m/s}=1.05 N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7BP%7D%7Bv%7D%3D%5Cfrac%7B4.20%20W%7D%7B4.0%20m%2Fs%7D%3D1.05%20N)
B) 3.03 T
The electromotive force induced in the circuit is:
(1)
where
B is the strength of the magnetic field
v = 4.0 m/s is the speed of the wire
L = 10.0 cm = 0.10 m is the length of the wire
We also know that the power dissipated is
(2)
where
is the resistance of the wire
Subsituting (1) into (2), we get
![P=\frac{B^2 v^2 L^2}{R}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BB%5E2%20v%5E2%20L%5E2%7D%7BR%7D)
And solving it for B, we find the strength of the magnetic field:
![B=\frac{\sqrt{PR}}{vL}=\frac{\sqrt{(4.20 W)(0.350 \Omega)}}{(4.0 m/s)(0.10 m)}=3.03 T](https://tex.z-dn.net/?f=B%3D%5Cfrac%7B%5Csqrt%7BPR%7D%7D%7BvL%7D%3D%5Cfrac%7B%5Csqrt%7B%284.20%20W%29%280.350%20%5COmega%29%7D%7D%7B%284.0%20m%2Fs%29%280.10%20m%29%7D%3D3.03%20T)
Extremophiles occur in all three domains of life: bacteria, archaea, and eukaryotes. Most extremophiles are microorganisms.
F=ma, in this case your force=-883 N and mass = 90 kg. F/m=a therefore acceleration=-883/90=-9.81 m/s/s
