It’s supposed to be gamma, what are your other options
The heat will leave the house, causing it to become colder. if it’s windy outside it will get colder in the house faster.
Answer:
Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.
In formula, this is written as:
where
vf is the final velocity
vi is the initial velocity
t is the time it takes for the object to accelerate from u to v
Note that acceleration is a vector, so it can also be caused by a change in the direction of the velocity, not only by a change in its magnitude.
Answer:
A) Fb = 671.3 N
B) The diver will sink.
Explanation:
A)
The buoyant force applied on an object by a fluid is given by the following formula:
Fb = Vρg
where,
Fb = Buoyant Force = ?
V = Volume of the water displaced by the object = 68.5 L = 0.0685 m³
ρ = Density of Water = 1000 kg/m³
g = 9.8 m/s²
Therefore,
Fb = (0.0685 m³)(1000 kg/m³)(9.8 m/s²)
<u>Fb = 671.3 N</u>
B)
Now, in order to find out whether the diver sinks or float, we need to find weight of the diver with gear.
W = mg = (71.8 kg)(9.8 m/s²)
W = 703.64 N
Since, W > Fb. Therefore, the downward force of weight will make the diver sink.
<u>The diver will sink.</u>
It is dangerous for children. Air bags are dangerous to children age 12 and under because the bag inflates at speeds up to 200 mph and that sudden blast of energy can severely injure or kill passengers who are too close to the air bag. If possible, children should ride in the center of back seat, properly restrained with a seat belt.
