The magnetic field strength will be 6.1 x 10⁻⁴ T.
What is magnetic field?The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.
The magnetic field strength is the magnitude of magnetic field in Tesla. It is related to velocity, magnitude of charge and force by the relation,
Magnetic force F = qVB
Given is the charge q = -8.8×10⁻²⁰ C, Force F = -5.2×10⁻¹⁶ N and the velocity v = 9.6×10⁶ m/s, then the magnetic field strength will be
B = -5.2×10⁻¹⁶/-8.8×10⁻²⁰ x9.6×10⁶
B = 6.1 x 10⁻⁴ T
Thus, the magnetic field strength will be 6.1 x 10⁻⁴ T.

On a frictionless horizontal air table, puck A (with mass 0.251 kg ) is moving toward puck B (with mass 0.371 kg ), which is initially at rest. After the collision, puck A has velocity 0.120 m/s to the left, and puck B has velocity 0.654 m/s to the right.
What was the speed vAi of puck A before the collision?
Calculate ΔK , the change in the total kinetic energy of the system that occurs during the collision.
(a) The speed of puck A before the collision is determined as 0.847 m/s.
(b) The change in the total kinetic energy of the system that occurs during the collision is 0.009 J.
Speed of puck A before the collisionThe speed of puck A before the collision is calculated from the principle of conservation of linear momentum as follows;
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.251u₁ + 0.371(0) = 0.251( -0.12) + 0.371(0.654)
0.251u₁ = 0.2125
u₁ = 0.2125/0.251
u₁ = 0.847 m/s to the right
Change in the total kinetic energy of the systemInitial kinetic energy = ¹/₂ x 0.251 x (0.847)² + ¹/₂ x 0.371 x (0) = 0.09 J
Final kinetic energy = ¹/₂ x 0.251 x (-0.12)² + ¹/₂ x 0.371 x (0.654)² = 0.081 J
ΔK.E = 0.081 - 0.09 = 0.009 J ≈ 0 J

Nitrogen oxides in car exhaust react with sunlight to produce
2 kg
Use 10 m/s2 for g
Answer:
See below
Explanation:
At point A the PE = mgh = 2 * 10 * 1 = 20 J
at point B, all of the PE , 20 J , is converted to Kinetic Energy
KE = 1/2 m v^2
20 = 1/2 (2)(v^2 )
20 = v^2 v = sqrt 20 = 4.47 m/s
for the friction part
vf = vo t + 1/2 a t^2 vf = final velocity = 0 (stopped)
vo = original velocity = 4.47 m/s
a = -1 m/s^2
0 = 4.47 t + 1/2 (-1) t^2
- .5t^2 + 4.47 t = 0
t ( -.5t+ 4.47) = 0 shows t = 4.47/.5 = 8.9 seconds

What is the law of conservation of momentum?According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
The given data in the problem is;
(m₁) is the mass = 2 kg
initial velocity (u₁) =5m/s
(m₂) is the mass = 0.5
(u₂) initial velocity = 0 m/s
(v) is the velocity =.?
According to the law of conservation of momentum;
Momentum before collision =Momentum after collision
[tex]\rm m_1u_1 + m_2u_2 = v(m_1 + m_2) \\\\ 2(5) + 0.5(0) = v(2 + 0.5)\\\\10 = 2.5v\\\\ v = \frac{10}{2.5} \\\\ v = 4 \ m/s[/tex]

Group the labels according to the type of force they describe
Contact, no contact or both
We can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.
What are some examples of these forces?There are many everyday examples to be used to describe each of these forces. A very common no contact force is gravity. The Earth's gravity exerts a force on all things near the planet, but it does not need to be in physical contact to exert this force, thus making gravity a no contact force. An example of a contact force would be if you were to push another person. You are exerting a force that requires physical contact.
Therefore, we can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.

5. A person on a trampoline jumps straight up. When the person is 3 m above the surface and
with upward velocity of 2.5 m/s, drops a ball. a) What is the speed of the ball at the time of
impact? b) How long before the ball impacts the surface of trampoline?
a)The speed of the ball at the time of impact will be 8.1 m/sec.
b)The time taken by the ball impacts the surface of trampoline will be 1.1 second.
What is speed?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. Its SI unit is m/sec.
Given data;
g( gravitational acceleration) = 9.81 m/s2
u (initial velocity of ball) = 2.5 m/s
h₁(initial height of the ball) = 3.0 m
v (speed of the ball at the time of impact ) ?
The time taken by ball for upward journey = u / g
t₁ = u / g
t₁ = (2.5 m/s) / (9.81 m/s2) =
t₁ =0.2548 s
From second equation of motion,upward vertical distance covered by ball is;
[tex]\rm h_2= \frac{1}{2} gt^2\\\\ h_2=\frac{1}{2} \times 9.81 \times (0.2548)^2\\\\ h_2=0.3184[/tex]
The total distance in the downward direction travelled;
[tex]\rm h_3=h_1+h_2 \\\\ h_3=3.0+0.3184 \\\\ h_3=3.3184 \ m[/tex]
The time taken for the downward motion is;
[tex]\rm t_2 = (\frac{2 \times h_3 }{g} )^\frac{1}{2}\\\\ t_2 = 0.825 \ m/sec[/tex]
The speed of the ball at the time of impact is found as;
[tex]\rm V=gt_2 \\\\ V= 9.81 \times 0.8225 \\\\ V= 8.07 \ m/sec[/tex]
The total time of the flight of ball is;
[tex]\rm t_3 = t_1+t_2 \\\\ t_3=0.2548+0.8225 \\\\ t_3=1.0774 \ sec[/tex]
Hence,the speed of the ball at the time of impact will be 8.1 m/sec and time taken by the ball impacts the surface of trampoline will be 1.1 second.

Answer:
110.4 v
Explanation:
Find the equivalent resistance of the two parallel circuits
R1 and R2 in parallel = R1 * R2 / (R1+ R2) = 1 ohm
similarly R4 and R5 = 4.77 ohms
Now you can add the three resistances into one (R3=10)
1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms
Now
V = IR
V = 7 amps * 15.77 ohm = 110.4 v
