1. Why do you think it is important for people to know when the tides will be high and/or low?
Many reasons. Here are a couple:
1.) Water depth for the draft of incoming ships/vessels so they do not run aground.
2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.
please can someone please help me with this!!
i’ll give 15 points!!
Answer:
Explanation:
Time is a major factor in how much force is being applied. so when there are crumple zones. they crumple and that takes a little longer in an impact and hence lowers the forces considerably :) safety first

Which of these is NOT a line on the tennis court?
Base line
Service line
Side line
Front line
Answer:
The answer would be Front Line
The base line, service line, and the side lines are the part of the tennis court however front line is not a part of the tennis court. Thus, the correct option is D.
What are the specifications of Tennis Court?
A tennis court is a 78ft long court, with a service line of 21ft from the net. The courts for singles tennis matches are 27ft wide in dimension, while the doubles matches courts are 36ft wide. The total playing area in tennis for a singles court is 2,106ft² and 2,808ft² for a doubles court.
The basic and important parts of a tennis court in both singles and doubles are the baseline, the center mark, the sidelines, the service lines, and the service boxes. The baseline is the boundary line at the ends of the tennis court, and the sidelines are the lines which mark the boundary line between in-bounds and out-of-bounds for both singles and doubles play.
Therefore, the correct option is D.

what is the correct equation for calculating kinetic energy?
1. kinetic energy = potential energy - total energy
2. kinetic energy = total energy - potential energy
3. kinetic energy = 1/2 x (total energy + potential energy)
4. kinetic energy = potential + total energy
Answer:
2. kinetic energy = total energy - potential energy
Explanation:
The total energy of a system is the addition of kinetic and potential energy of the system. Kinetic energy can be regarded as form of energy posses by an object when it's in motion
Total energy = kinetic energy + potential energy
(If we make Kinectic energy the subject of the formula, we have)
kinetic energy = total energy - potential energy

Para pagar la entrada al circo y comprar palomitas: Daniela y María van a cooperar con $65.50 cada una y Francisco y Javier con $69.50 cada uno. ¿Cuánto dinero van a reunir?
Answer:
Reunirán $270.
Explanation:
Para pagar la entrada al circo y comprar palomitas Daniela y María van a cooperar con $65.50 cada una. Entonces para calcular el dinero que van a reunir entre ambas debes sumar lo que aporta cada una:
$65.50 + $65.50= $131
Por otro lado, Francisco y Javier van a cooperar con $69.50 cada uno. De igual manera, para calcular el dinero que van a reunir entre ambos debes sumar lo que aporta cada uno:
$69.50 + $69.50= $139
Para conocer el dinero total recaudado, debes sumar lo que aportan tanto ellas como ellos. Esto es:
$131 + $139= $270
Reunirán $270.
1. What is the speed of an object and the direction it is moving?
Answer:
Velocity
Explanation:
The pressure at the bottom of a lake is 300 000 N/m2 more than at the surface of the lake. The lake is fresh water (density = 1000 kg/m3).
Answer:
h = 30.61 m
Explanation:
In this problem they indicate the pressure at the bottom of the lake and the density of the water, for which they must ask what is the depth of the lake.
The pressure is given by the expression
P = [tex]P_{atm}[/tex] + rho g h
P - P_{atm} = rho g h
The gauge pressure value is P- P_{atm} = 3 105 N / m²
h = [tex]\frac{P - P_{atm}}{ \rho \ g}[/tex]
let's calculate
h = [tex]\frac{3 \ 10^5}{1000 \ 9.8}[/tex]
h = 30.61 m

Calculate the momentum of a 1000 kg sports car traveling at 30 m/s.
Answer:
30,000 kgm/s
Explanation:
m = 1000 kg
v = 30 m/s
Plug those values into the equation:
p = mv
p = (1000 kg)(30 m/s)
p = 30,000 kgm/s
The momentum of a 1000 kg sports car traveling at 30 m/s is 30,000 kgm/s.Linear momentum = Mass x Speed.
What is the momentum?The product of an object's mass, m, and its velocity, v, is the vector quantity known as linear momentum. It is represented by the letter "p," which is also used to denote momentum.
Mass of car = 1000 kg
Speed by which car moves = 30 m/s. The momentum of the car =?
Recall that:
Linear momentum = Mass x Speed
= 1000 kg x 30 m/s.
= 30,000 kgm/s
The sum of an object's mass (m) and velocity (v) is known as the object's linear momentum. An equation can be used to explain this relationship. Momentum is defined as the body's mass times its velocity. P = m times v, etc.
Therefore, the momentum of a 1000 kg sports car is 30,000 kgm/s if travels at 30 m/s.

Explanation:
acontainer is filled whith mercury to alevel of 10m whit water to alevel of 8m and whit oil to alevel of 5m the densities oil ,water and mercury are 0.8g/cm³,1g/cm³ and 13.6g/cm³ calculate the total pressure exerted by the liquids at the base
Answer:
1450.4 KN[tex]m^{2}[/tex]
Explanation:
Pressure = ρhg
where: ρ is the density of the liquid, h is the height and g the force of gravity.
Total pressure exerted by the liquids at the base = Pressure of oil + Pressure of water + Pressure of mercury
So that,
i. Pressure of oil = ρhg
(ρ = 0.8 g/cm³ = 800 kg/m³)
= 800 x 5 x 9.8
= 39200
Pressure of oil = 39200 N[tex]m^{2}[/tex]
ii. Pressure of water = ρhg
(ρ = 1 g/cm³ = 1000 kg/m³)
= 1000 x 8 x 9.8
= 78400
Pressure of water = 78400 N[tex]m^{2}[/tex]
ii. Pressure of mercury = ρhg
(ρ = 13.6 g/cm³ = 13600 kg/m³)
= 13600 x 10 x 9.8
= 1332800
Pressure of mercury = 1332800 N[tex]m^{2}[/tex]
So that,
Total pressure exerted by the liquids at the base = 39200 + 78400 + 1332800
= 1450400
= 1450.4 KN[tex]m^{2}[/tex]
Total pressure exerted by the liquids at the base is 1450.4 KN[tex]m^{2}[/tex].
