The answer is true hope that helped!!
Answer:
- The temperature of 10°C will be experienced at an altitude of 2.52 km
- The temperature of 0°C will be experienced at an altitude of 4.15 km
Explanation:
Lapse Rate = -6.5°C/km of ascent.
Lapse Rate = Temperature difference/altitude difference
For the 10°C,
Temperature difference = 10 - 27 = -17°C
-6.5 = -17/(difference in altitude between the two points)
Difference in altitude = 17/6.5 = 2.52 km
For 0°C,
Temperature difference = 0 - 27 = - 27°C
-6.5 = -27/(difference in altitude between the two points)
Altitude difference = 27/6.5 = 4.15 km
Answer:
2.8 N
Explanation:
Fp = 7.7 N
mA = 12.1 kg
mB = 7 kg
Let a be the acceleration and Fc be the contact force between A and B.
By the free body diagram, use Newton's second law
Fp - Fc = mA x a ..... (1)
Fc = mB x a ..... (2)
Adding both the equations
Fp = (mA + mB) x a
7.7 = (12.1 + 7) x a
a = 0.4 m/s^2
Substitute this value in equation (2), we get
Fc = 7 x 0.4 = 2.8 N
Thus, the contact force between the two blocks is 2.8 N.
Explanation:
The acceleration of the body in terms of the gravitational constant G is G.
According to Newton's law of universal gravitation;
F = Gm1m2/r^2
G = gravitational constant
m1 = mass of the first body
m2 = mass of the second body
r = distance between the two bodies
Substituting values to find the force on the two bodies;
F = G × 1 × 2/1^2
F = 2G
For the 2 Kg mass
F = ma
m = mass
a = acceleration
F = gravitational force
Hence,
2G = 2a
a = 2G/2
a = G

The scalar operates only on the magnitude of the vector.
So the length of the vector may change ... becoming longer
or shorter ... but its direction doesn't change.
