A simple thermocouple circuit, which is composed of type-J thermocouples, is used to measure the temperature of a gas. The open circuit voltage, V0, oscillates in a sinusoidal fashion with a mean of 4.997 mV, an amplitude of 0.541 mV, and a frequency of 2.1 Hz. The measurement system has the time constant τ = 1.7 s. The reference junction temperature is measured with a platinum RTD (a = 0.003927 °C^-1) where R = 1.0275 W and R0 = 1.0000 W with T0 = 25 °C. Calculate the following quantities:

a. The mean gas temperature.
b. The amplitude of the fluctuating gas temperature.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
