Answer:
vpg = 0.064 N
Explanation:
Upthrust = Volume of fluid displaced
upthrust liquid on the cube g=10ms−2
vpg =0.2 x 0.2 x 0.2 x0.8 x 10= 0.064N
vpg = 0.064 N
hope it helps.

Answer: C
Period and wavelength
Explanation:
Mechanical wave requires a medium for it propagation transfering energy through a medium. The waves can move over long distances but limited due to the movement of the medium of the material causing the oscillating material not move far. This depends on the period and the wavelength of the wave.
Answer:
Acceleration a=0.5 m/s²
Explanation:
Given data
Mass m=12,900 kg=1.29×10⁴kg
Thrust of engine F=28,000 N=2.8×10⁴N
gravitational acceleration g=1.67 m/s²
To find
Acceleration
Solution
As we know that
The net force can be given as
From Newtons second law of motion we know that
