Answer:
Explanation: societal law is A statement about how things act in the natural world. the wire and electro magnet need to touch in question 2. a decrease in spee decreases kinetic energy. the test variable was the distance traveled by the scrunched paper.
Answer:
(A) Force on the object will be 58.85 N
(B) Apparent weight will be equal to 57.21 N
Explanation:
We have given mass of Neptune m = 1026 kg
Radius R = 25000 Km
Time period = 16 hour
We know that 1 hour = 3600 sec
So 16 hour = 16×86400 = 57600 sec
Acceleration due to gravity at north pole of Neptune 
(A) Mass of the object m = 5.5 kg
So gravitational force on the object 
(B) Velocity will be equal to 
Apparent weight of the object will be equal to 

Answer:
a) He found the same value of q/m for different cathode materials.
b) y =
, c) v = 
Explanation:
In Thomson's experiments he was able to measure the deflection of the light beam under the effect of the magnetic field and with these results find the e / m relationship, which in all cases is the same, therefore the most important conclusion is that the value e E / m is constant for all materials.
b) In the part of the plates the electrons are accelerated by the electric field,
F = ma
- e E = m a
a = - (e/m) E₀
the distance traveled is
X axis
x = v₀ t
the separation of the plates is x = d
t = vo / d
Y axis
y = v_{oy} t + ½ to t²
y = ½ a t²
y =
c) In this case there is a magnetic field B₀ and the electrons have no deflection
F = - e E + e v x B
if there is no deviation F = 0
e E = e v B
v = 
<h3><u>Answer;</u></h3>
Choose a heavier bat
<h3><u>Explanation</u>;</h3>
- Momentum is a vector which is often defined as the product of an object’s mass with its velocity.
- Two factors affecting momentum is the mass and velocity of the object. An object that has a low velocity and a small mass produce minimal momentum because it would take a small force and/or time to stop it.
- Therefore, choosing a heavier bat would increase the momentum of the plate.
