Dimension of specific heat capacity

Luden [163]

Answer:

The specific heat of a substance (per unit of mass) has dimension L. T. Θ−1, or (L/T)2/Θ. Therefore, the SI unit J/K/kg is equivalent to metre squared per second squared per kelvin (m2 K−1 s−2).

1) Beth rode the Flying Saucer ride at her favorite amusement park. The ride hung from a rod and swung back and forth while simu

quester [9]

Since Beth rode the Flying saucer ride which is spinning on its axis while axis is moving to and fro as well, so here Beth will experience two motions in this case

(i) Spinning motion

(ii) Rotational motion

Jill and Scott both traveled for 30 min

So time of motion for both is 0.5 h as we know that 1 h = 60 min

Now from the formula of speed we know that

$speed = \frac{distance}{time}$

Speed of Jill

$v_1 = \frac{5}{0.5} = 10 km/h$

speed of Scott

$v_2 = \frac{10}{0.5} = 20 km/h$

so correct answer is

B) Scott had the faster speed since he rode at 20 k/h while Jill only traveled 10 km/h.

Since we know that acceleration is rate of change in velocity

So here we can say that every motion where velocity changes with time then it is an accelerated motion.

Now change in velocity occurs when either the magnitude will change or its direction will change because here velocity is a vector quantity and it will change with magnitude and direction both.

so here due to oval path the direction of velocity will changes at many points and hence it will be an accelerated motion.

so correct answer is

C) James was right since the car changed direction during the race.

A 70.0-kg person rides in an elevator while standing on a scale. the scale reads 896 n. what is the magnitude and direction acce

Ksju [112]

If the elevator was stationary, the scale would read exactly the weight of the person:
$W=mg=(70 km)(9.8 m/s^2)=686 N$
However, the elevator is moving with an acceleration a, so the scale reads a new value of the weight, which we call W'. Newton's second law becomes
$W' = ma'$
where a' is actually the total acceleration of the person, so it's the sum of the acceleraion of the elevator and of the gravitational acceleration: $a'=a+g$
Taking the direction of g (downward) as the positive direction, we can find the value of a:
$W' = m(a+g)$
$a= \frac{W'}{m}-g= \frac{896 N}{70 kg}-9.8 m/s^2=3 m/s^2$
So, the acceleration of the elevator is $3 m/s^2$ , with same sign of g, so it's directed downward as well.
