Pressure is define as force per unit area. Mathematically expressed as,
P=F/A.
We are given, a mass of the ball equal to
m=1.6kg and an Area of 1.1cm2=1.1(
)m2
To calculate for the force exerted by the finger to the ball, it is simply equal to the weight of the ball. Mathematically,
F=W
Weight of the ball can be calculated as,
W= ma
where m=mass of the object and a is the acceleration due to gravity (9.8m/s).
Then, the Weight of the ball which is equalt to the force exerted by the finger,
W=F=(1.6 kg x 9.81)=15.696 N
Then Pressure would be,
P=(15.696N/1.1(.1(
)m2))
P=
142690.91 N/m2=142690.91 Pa

i don,t think so the averge of the car speed is faster
Answer:
(A) A pitch that is higher than the pitch actually produced
Explanation:
Doppler effect
According to the research, the correct answer is that higher latitudes are conditions that can cause hurricanes to change direction.
<h3>What are hurricanes?</h3>
It is a meteorological phenomenon that usually originates in the tropical areas of the lower atmosphere, being a wind of extraordinary force that forms a whirlwind.
In this sense, the direction of these winds is influenced by the rotation of the Earth (Coriolis effect) and that as they move a little towards the higher latitudes, the direction winds are reversed and blow from west to east.
Therefore, we can conclude that the condition that affects the direction of hurricanes is when these tropical phenomena reach the highest latitudes.

The shortest frequency of light required to remove an electron from a sample of ti metal if the binding energy of titanium is 3. 14 × kj/mol will be v = 0.47 * Hz
Binding energy, amount of energy required to separate a particle from a system of particles or to disperse all the particles of the system. Binding energy is especially applicable to subatomic particles in atomic nuclei, to electrons bound to nuclei in atoms, and to atoms and ions bound together in crystals.
Work function is defined as the minimum amount of energy needed to remove an electron from the atom. So, the minimum energy required to remove an electron is called the Work function.
plank's constant = 6.62 × kg/s
Binding energy = 3. 14 × kj/mol
Energy = plank's constant * frequency
3. 14 × = 6.62 × * v
v = 3. 14 × / 6.62 ×
v = 0.47 * Hz
