Calculate (a⃗ ×b⃗ )⋅c⃗ for the three vectors a⃗ with magnitude a = 5.14 and angle θa = 23.0 ∘ measured in the sense from the +x - axis toward the +y - axis, b⃗ with b = 4.20 and θb = 63.8 ∘, and c⃗ with magnitude c = 5.96 and in the +z - direction. vectors a⃗ and b⃗ are in the xy-plane.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

answer: $1794
