To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ
sec θ = 1 / cos <span>θ
csc </span>θ = 1 / sin θ<span>
Using these identities:
</span>cot θ ∙ sec θ = (cos θ / sin θ ) (<span> 1 / cos </span><span>θ)
</span>
We can cancel out cos <span>θ, leaving us with
</span>cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc <span>θ</span>
Answer:
Magnitude of the force is 4350N
Explanation:
As the woman accelerates at a distance of 22 m to go from rest to 62.5 m / s, we can use the kinematics to find the acceleration
v² = v₀² + 2 a x
v₀ = 0
a = v² / 2x
a = 62.5²/(2 × 22)
a = 88.78m/s²
the time you need to get this speed
v = v₀ + a t
t = v / a
t = 62.5 / 88.78
t = 0.704s
Let's caculate the magnitude of the force
F = ma
= 49 × 88.78
= 4350.22
≅ 4350N
Magnitude of the force is 4350N
t = 1,025 s
a = 55.43 m / s²
Answer:
a) 
b) 
c) 
Explanation:
Given:
- voltage of the battery,
- energy storage capacity of the battery,
- speed of the car,
a)
power drawn by the car, 
<u>Now the Current delivered to the motor:</u>
we the relation between the power and electrical current,
b)
<u>Distance travelled before battery is out of juice:</u>
we first find the time before the battery runs out,
Now the distance:
c)
When the head light of 55 W power is kept on while moving then the power consumption of the car is:
<u>Now the time of operation of the car:</u>
<u>Now the distance travelled:</u>
