Answer:
With the addition of the pipe we have a greater torque.
Explanation:
We need to complete the description of the problem, searchin in internet we have:
"Sometimes, even with a wrench, one cannot loosen a nut that is frozen tightly to a bolt. It is often possible to loosen the nut by slipping one end of a long pipe over the wrench handle and pushing at the other end of the pipe. With the aid of the pipe, does the applied force produce a smaller torque, a greater torque, or the same torque on the nut?"
With the addition of the pipe we have a greater torque, as it increases the distance or radius of torque.
We know that torque is defined, as the product of force by distance, in this way we have:
T = F * d
where:
T = torque [N*m]
F = force [N]
d = distance [m]
We can see in the above equation, that increasing the distance increases torque proportionally.
Answer:
<h2>470.59 kg</h2>
Explanation:
The the mass of the car can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>470.59 kg</h3>
Hope this helps you
Answer:
1. at least two charged interacting parts
2. from the electric fields of charged subatomic particles
3 an arrow released from the bow
4Electrical fields of charged particles interact, bonding those with opposite charges.
5 the interaction of the electric fields of protons and electrons
6 The energy stored in the system increases.
7 Kinetic energy increases because the magnets move in the direction of the field.
8 Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.
9
The energy stored in the field decreases because the magnet moves in the direction of the field.
10 The energy stored increases and then decreases.
11 The wire was not connected to the source.
12 The electromagnet will become more powerful.
the rest are written, hope this helps (:
Explanation:
If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet
Answer:
(a) 10 s
(b) 236.5 m
(c) Kathy's speed = 47.3 m/s
Stan's speed = 42.9 m/s
Explanation:
<u>Given:</u>
= initial speed of Kathy = 0 m/s
= initial speed of Stan = 0 m/s
= acceleration of Kathy = 
= acceleration of Stan = 
<u>Assumptions:</u>
= final speed of Kathy when see catches Stan
= final speed of Stan when Kathy catches him
= distance traveled by Kathy to catch Stan
= distance traveled by Stan when Kathy catches him
= time taken by Kathy to catch Stan = 
= time interval in which Kathy catches Stan = 
Part (a):
Kathy will catch Stan only if the distances traveled by each of them are equal at the same instant.
Hence, Kathy catches Stan after 11 s from the Stan's starting times.
Part (b):
Distance traveled by Kathy to catch Stan will be distance the distance traveled by her in 10 s.
Hence, Kathy traveled a distance of 236.5 m to overtake Stan.
Part (c):
The speed of Kathy at the instant she catches Stan is 47.3 m/s.
The speed of Stan at the instant Kathy catches him is 42.9 m/s.
