If the net force on a 75 - N object is 375 N from the left in what direction will the object move

2 answers:

6 0

We really don't care what the size of the force is or what the object weighs.
neither of those numbers has any effect on the answer.

If the net force on an object is FROM the left, then no matter
which way the object is already moving, it will ACCELERATE
to the right. If the object isn't moving (its speed is zero), then
its speed will increase, and it will move to the right.

It would move to the right because the force is being applied from the left.

A 570 kg elevator accelerates downwards at 1.5 m/s2 for the first 13 m of its motion.

jeka94

Mass of the elevator (m) = 570 Kg
Acceleration = 1.5 m/s^2
Distance (s) = 13 m
Let the force be F.
We know, F = ma,
Therefore, F = (570 × 1.5) N = 855 N
Angle between distance and force (θ) = 0°
We know, work done = F s Cos θ
Therefore, work done by the cable during this part
= (855 × 13 × Cos 0°) J
= (855 × 13 × 1) J
= 11115 J

Answer:

11115 J

Hope you could get an idea from here.

We can model the human back as a pivoted rod?

3241004551 [841]

Answer:

So the answer is yes, we can the back be shaped like a spinning rod

spinal column that is approximated by a long and narrow rod,

Explanation:

The bone system of the body is very well modeled in physics, the back has a spinal column that is approximated by a long and narrow rod, this rod is fixed in the lower part to the coccyx and has a weight in the upper part (head), this rod has longitudinal vertical movement and twisting movement around the lower part of the bar.

So the answer is yes, we can the back be shaped like a spinning rod

A current of 200mA through a conductor converts 40 joules of electrical energy into heat in 30 seconds determine the potential d

gladu [14]

Answer:

V = 6.65 [volt]

Explanation:

We must first find the power generated, power is defined as the amount of energy consumed or generated in a given time.

$P=\frac{E}{t}$

where:

P = power [w]

E = energy = 40 [J]

t = time = 30 [s]

$P =40/30\\P = 1.33[w]$

Now we can calculate the voltage or potential drop by means of the power, the power is calculated by means of the product of the voltage by the current.

$P =V*I$

where:

V = voltage [volts]

I = current = 200mA = 0.2 [A]

$V = P/I\\V = 1.33/0.2\\V = 6.65 [Volt]$
