Answer:
The acceleration is 10 m/s²
Explanation:
The question seeks to show the relationship between force, mass and acceleration. Hence, the formula to be used here is that of force which is shown below
F = ma
where F is the force (800 N)
m is the mass (80 kg)
a is the acceleration (unknown)
From the formula above (Force = mass multiplied by acceleration)
800 N = 80 kg × a
a = 800 ÷ 80
a = 10 m/s²

Explanation:
Physical Property: A property of matter that can be seen, felt, tasted, smelled, or heard.
Physical Change: The change of an object of matter's physical property/properties.
Chemical Property: An element/object of matter's internal property/properties
Chemical Change: An element/object of matter's internal property/properties being altered or changed

Answer:
The distance at which nose of the vehicle will the shock wave impinge upon the ground is approximately 23km
Explanation:
Let
u be Mach angle
M be Mach Number = 2.5
h be altitude = 10km
d be distance between nose of the vehicle with which the shock wave impinge upon the ground
Using;
Sin u = 1/M
u = arcSin (1/M)
u = arcSin (1/2.5) = 23.58°
Using angle at a point rule = 90°
90 - 23.58 = 66.42°
Tan A = opp/adj
Tan 66.42° = d/10
2.2911 * 10 = d
d = 22.911km ≈ 23km
Answer:The force of buoyancy equals density of liquid times acceleration due to gravity times volume of liquid replaced. So buoyancy is directly proportional to gravity, and you would float just as well in 5G as 1G. ... A simpler way to look at it is: you float because gravity attracts water more than it attracts your body.
Explanation: i dont know if this helps i hope it does have a nice day.
