Answer: Option (b) is the correct answer.
Explanation:
Kinetic energy is the energy of an object or particle when it is in motion.
Mathematically, Kinetic energy = 
It is given that toy truck has mass = 0.75 kg, and velocity = 4 m/s.
Calculate the kinetic energy as follows.
Kinetic energy =
= 
= 
= 
= 
or, Kinetic energy = 6 joules
Thus, we can conclude that kinetic energy of toy truck is 6 J.
I don't know what the tables you have look like but her <span>displacement</span> would be -1m
Answer:
The Ferris wheel's tangential (linear) velocity if the net centripetal force on the woman is 115 N is <u>3.92 m/s</u>.
Explanation:
Let's use <u>Newton's 2nd Law</u> to help solve this problem.
The force acting on the Ferris wheel is the centripetal force, given in the problem: 
.
The mass "m" is the <u>sum</u> of the man and woman's masses: 
.
The acceleration is the centripetal acceleration of the Ferris wheel: 
.
Let's write an equation and solve for "v", the tangential (linear) acceleration.
The Ferris wheel's tangential velocity is 3.92 m/s.
No. Force isn't something you can enclose in a box, an envelope,
or a bottle.
A stick of dynamite contains some amount of a chemical compound which,
when triggered by enough heat or shock, undergoes a chemical reaction
that proceeds very rapidly, and generates a large quantity of gases before
the gases can dissipate. This creates very high pressure around the reaction,
and it's this pressure in a small volume that exerts great force for a very short
time. The whole process is often described as an "explosion".
Answer:
Explanation:
Force on the electron = q ( v x B )
q = - 1.6 x 10⁻¹⁹
v = (5.9i−6.4j)×10⁴
B = (−0.63i+0.65j)
v x B = (5.9i−6.4j)×10⁴ x (−0.63i+0.65j)
= (3.835 - 4.032 ) x 10⁴ k
= - 1970 k
Force on the electron = q ( v x B )
= - 1.6 x 10⁻¹⁹ x -1970 k
= 3.152 x 10⁻¹⁶ k
z-component of the force on the electron
Fz = 3.152 x 10⁻¹⁶ N
