A :-) F = ma
Given - m = 95 kg
a = 2.2 m/s^2
Solution -
F = ma
F = 95 x 2.2
F = 209

.:. The force is 209 N

I need to know the correct answer please ?
mrs_skeptik [129]

Answer:

675 Pa.

Explanation:

F = 5+2cos(15t) kN

Area (a) = 8*10-3 m2

Now at t =4 sec

            F= 5+2cos(60)

             = 5+2*0.5

              = 6  kN

Now ,force efficiency is 90%.

Hence,the effectively transmitted force,

            Fe = 0.90*6

                = 5.4 kN

Hence,pressure is given as,

            P = Fe/a

                = 5.4*10^3/(8 *10^-3))

              P = 675 Pa....answer

The forces on one of the wires will be 0.000264 N.It is the field sensed around a moving electric charge that gives rise to the magnetic force.

<h3>What is a magnetic field?</h3>

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

I is the current = 6.50 A

B is the magnetic field=f 2.71 X 10⁻⁵ T

The force on the wire is;

\rm F= BIL \\\\\ F=2.71 \times 10^{-5} \ T \times 6.50 \  A \times 1.50 \ m \\\\\ F=0.000264225 \ N

Hence, the force on one of the wires will be 0.000264 N.

What braking technique slows the vehicle as quickly as possible without locking brakes or losing traction
-Dominant- [34]

Answer: Cadence braking or Stutter braking is the braking technique slows the vehicle as quickly as possible without locking brakes or losing traction.

Explanation: To find the answer, we need to know more about the Cadence breaking.

<h3>What is cadence braking?</h3>
  • It's a braking technique, that includes, pumping the brake pedal and which used to allow a vehicle to steer as well as brake on a slippery surface.
  • It is used in the case of an emergency or sudden braking is needed.
  • In this technique, traction is limited to reduce the effect of skidding from road wheels locking up under braking.

Thus, from the above given data, we can conclude that, Cadence braking or Stutter braking is the braking technique slows the vehicle as quickly as possible without locking brakes or losing traction.
