D th
Explanation:
D B. The force applied to the ball is a balanced force.
We know that:
1 mile = 1.61 km
1 gal = 3.8 L
Therefore converting the fuel efficiency rates:
highway = (28.5 km/L) * (1 mile / 1.61 km) * (3.8 L / 1
gal) = 67.27 mile / gal
<span>city = (22.0 km/L) * (1 mile / 1.61 km) * (3.8 L / 1 gal)
= 51.93 mile / gal</span>
Whichever person or group can build something to protect the egg from cracking when it is dropped from a high spot without it breaking or cracking wins
Answer:
Explanation:
mass of the fellow ( m ) = 66kg
acceleration of fellow a
v = u + at
4.5 = 0 + a x 2
a = 4.5 /2
= 2.25 m / s²
Net force acting on fellow in upward direction by the surface of elevator
R - mg where R is reaction force of the surface of the elevator
Applying Newton's law of motion
R - mg = ma
R = m (g +a )
= 66 x ( 9.8 + 2 )
= 778.8 N
This will be the scale reading .
