Explanation:
Another way to perceive this is 1 G = 9.81 Newtons per Kilogram so 50 G =490.5 Newtons per Kilogram. The 100 gram apple at 1 G has 0.981 Newtons of force and at 50 G has an apparent weight of 5 KG or 49.05N.
Answer:
2 L, L, 2 L/3
Explanation:
For a pipe of length l open at both ends, the length of the pipe is given by :

or

For first pitch tone, n = 1

For first pitch tone, n = 2


For first pitch tone, n = 3


So, the wavelengths of the three lowest-pitch tones produced by this pipe are 2 L, L, 2 L/3 respectively. Hence, the correct option is (d)
ANSWER:
250 J
STEP-BY-STEP EXPLANATION:
F = 20N is required to stretch the spring by 4 meters
We know that the force is equal to:

We solve for k (spring constant):

The work done in stretching the spring is given by the following equation (in this case the stretch is 10 meters:

The work required is 250 joules.
Answer:
0.240 J/g/°C
Explanation:
q = mCΔT
47.3 cal = (55.00 g) C (15.0°C)
C = 0.0573 cal/g/°C
Usually, specific heat is measured in J/g/°C, so we can convert:
C = 0.0573 cal/g/°C × 4.184 J/cal
C = 0.240 J/g/°C
