Answer:
Explanation:
1. 
= 
* cos
⇒ 16*cos32 ≈ 13.6 m/s (13.56)
2. 
= * sin ⇒ 16* sin32 ≈ 9.4 m/s
3. 
= 
= 
(the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
≈ 3.6677+1.5 ≈ 5.2m
4. 
= 
=
≈ 23.5m (23.47)
5. -
answer 4 could be wrong, not certain about that one and i don't know 5
Answer:
Because of heavy mass
Explanation:
When force acts on a body it tends to accelerate the body. The acceleration produced in the body depends on two things:
1). Magnitude of force
2). Mass of the body
F= ma
⇒ a = F/m
As the force exerted on earth and another object are the equal in magnitude but opposite in direction. This forces will accelerate the object toward the earth but can't accelerate the earth as earth has very high mass.
a = F/m
This force tends to accelerate the earth but but due to earth's inertia the earth does not accelerate.
The maximum speed of Tim is 16.95 m/s.
The given parameters:
- Mass of the rope, m = 71 kg
- Tension on the rope, T = 220 N
- Coefficient of kinetic friction, = 0.1
- Time of motion, t = 8 s
<h3>What is Newton's second law of motion?</h3>
- Newton's second law of motion states that, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The net force on Tim is calculated by applying Newton's second law of motion as follows;
Thus, the maximum speed of Tim is 16.95 m/s.

Answer:
The resistance is found to be 6Ω
The current is found to be 0.66 A
Explanation:
The resistance of a conductor in terms of its dimensions is given as:
R = ρL/A
where,
R = resistance = ?
ρ = resistivity = 3 x 10⁴ Ω.m
L = Length = 4 mm = 0.004 m
A = Cross-sectional area = 0.2 mm² = 0.2 x 10⁻⁶ m²
Therefore,
R = (3 x 10⁴ Ω.m)(0.004 m)/(0.2 x 10⁻⁶ m²)
<u>R = 6 Ω</u>
Now, the potential difference between both ends of the resistor is:
ΔV = 16 V - 12 V = 4 V
Now, from Ohm's Law:
V = IR
I = V/R
I = 4 V/ 6 Ω
<u>I = 0.66 A</u>
Answer:
false
Explanation:
this is what google said
No because the path the electricity needs to follow is broken. In a parallel circuit, electricity has more than one path to follow. Electrons can follow different paths as they flow from the negative side of the battery to the positive side.
