Answer:
The depth and acceleration are 0.1919291 ft and 3.61 m/s².
Explanation:
Given that,
Density of block 
Density of fluid 
We need to calculate the depth
Using balance equation
....(I)
We know that,
The density is


Put the value of m in equation (I)



Put the value into the formula



We need to calculate the acceleration
Using formula of net force



....(II)
Put the value in the equation (II)


Hence, The depth and acceleration are 0.1919291 ft and 3.61 m/s².
The correct answer is: (A) An Atmosphere
Explanation:
The atmosphere of Venus is almost ninety times denser than that of Earth. Due to Venus' denser atmosphere and chemical composition (as its atmosphere comprises of over 96% of Carbon dioxide), it experience an immense greenhouse effect. That is why its surface temperature remains higher than 470°. At that very high temperature, it is impossible to have life on the surface of Venus.
1. make good decisions
2. explosive
3. favorable
answered these on edge. also, you marked this as physics even though its english. might wanna watch out for that lol, so youll get a quicker answer
Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.
Explanation:
(a) Draw a free body diagram of the cylinder at the top of the loop. At the minimum speed, the normal force is 0, so the only force is weight pulling down.
Sum of forces in the centripetal direction:
∑F = ma
mg = mv²/RL
v = √(g RL)
(b) Energy is conserved.
EE = KE + RE + PE
½ kd² = ½ mv² + ½ Iω² + mgh
kd² = mv² + Iω² + 2mgh
kd² = mv² + (m RC²) ω² + 2mg (2 RL)
kd² = mv² + m RC²ω² + 4mg RL
kd² = mv² + mv² + 4mg RL
kd² = 2mv² + 4mg RL
kd² = 2m (v² + 2g RL)
d² = 2m (v² + 2g RL) / k
d = √[2m (v² + 2g RL) / k]
