<span>B) equal pressures are applied from your foot to the pedal to the brake pads.
That would be the answer.

Answer:
0.96 kWh
Explanation:
First of all, we can find the power of the appliance using the formula:
where
V = 120 V is the voltage of the source
I = 2 A is the current
Substituting,
Now we want to find the amount of energy used by the applied in a time of
t = 4 h
The amount of energy is given by
where
P = 0.24 kW
t = 4 g
Substituting,
Answer:
x- component = Fx= 4N
y - component= Fy= 3N
Explanation:
Fx=Fcos∅= 5cos 37= 3.99≅4N
Fy=F sin∅= 5 Sin37= 3.009≅3.01N
the dog pulls the pillow at an angle 37 degrees to the horizontal means it pulls it at an angle 37 degrees with the x- axis.if the line of the force represents the vector F then its horizonatal and vertical components wil be along x-axis and y-axis ie Fx and Fy.
as sin∅= Perpendicular/ Hypotenuse
but we have force F and Fy
so sin∅= Fy/F
or Fy= Fsin∅---------eqA
similarly cos∅= base /hpotenuse
cos∅= Fx/F
Fx= Fcos∅----------eq B
eq A and eq B can be used to determine the values of the rectangular components of the force making an angle with the horizontal
Answer:
240000 mph² or miles/hour²
Explanation:
<em>Use the formula</em>
<h3>acceleration = change in velocity ÷ time</h3>
change in velocity = 300 mph - 0 mph (final velocity - intial velocity)
time = 0.00125 hours
<em>Substitute the values into the formula:</em>
acceleration = 300 ÷ 0.00125 = 240000 mph²
<span>Isotopes of argon. Argon (Ar) has 24 known isotopes, from 30Ar to 53Ar and 1 isomer (32mAr), three of which are stable, 36Ar, 38Ar, and 40Ar. On the Earth, 40Ar makes up 99.6% of natural argon.</span>
