Multiple choicedetermine the difference in the speed of sound in hydrogen at 0°c and in air at 30°c. a.)934 b)940 also indicate if it is faster or slower. a.)faster b.)slower

934 m/s and it is faster in hydrogen than in air

Explanation:

Speed of sound in gas is given by the formula

here we know for hydrogen

M = 2 g/mol

R = 8.31 J/mol k

T = 0 degree C = 273 K

now we will have

Now for air we know that

M = 29 g/mol

R = 8.31 J/mol k

T = 30 degree C = 303 K

now we will have

so the difference in the speed is given as

so the closest answer is 934 m/s and it is faster in hydrogen than in air

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
