Answer:
density
Explanation:
because it high salinity
Salinity and temperature of ocean water determines density of ocean water.
What is density?The density, of a substance, exists in its mass per unit volume. The symbol most often utilized for density is ρ, although the Latin letter D can also be utilized.
Increases in the temperatures of surrounding entities like ice and an increase in precipitation count fresh water into the ocean, which decreases the salinity. ocean water with lower salinity lives lighter in density and won't sink as much as denser water. This method also varies the ocean currents. The temperature has a greater influence on the density of ocean water than salinity does. So a layer of water which is having higher salinity can even float on top of the water with the one having lower salinity if the layer with more increased salinity exists quite a bit warmer than the lower salinity layer.

A 100-meter sprint is a race using only the straight side
of a racetrack. A 400-meter sprint is a race that makes
one complete lap around a racetrack. Why are velocity
and speed the same for a 100-m sprint but not a 400-m
sprint?
Answer: : it is so because velocity and speed differ each other by direction. in a 100 m sprint race ,the person moves in a straight path without changing its direction where as in a 400 m race , the person moves in a lap around the race track and the direction changes as he turns according to the race track.

Where is the weight of an object more on earth, Equator or poles? Why?
Answer:
The weight of an object at the poles is more than the weight of the object at the equator
Explanation:
The shape of the Earth is an ellipsoid such that the distance from the North and South poles to the Earth's center, R₁, is less than the distance from the Equator to the center of the Earth, R₂
The weight of an object is given by the universal gravitational law as follows;
[tex]Weight = F_{gravity} =G\times \dfrac{M \cdot m}{R^{2}}[/tex]
Where;
[tex]F_{gravity}[/tex] = The force of gravity = The weight of an object
G = The universal gravitational constant
M = The mass of the Earth
m = The mass of the object
R = The radius of the Earth
Where R₁ < R₂, we have;
The weight at the Poles, W₁ = [tex]G\times \dfrac{M \cdot m}{R_1^{2}}[/tex]
The weight at the Equator, W₂ = [tex]G\times \dfrac{M \cdot m}{R_2^{2}}[/tex]
We have;
[tex]\left(G\times \dfrac{M \cdot m}{R_1^{2}} \right) > \left(G\times \dfrac{M \cdot m}{R_2^{2}} \right) \because R_1 < R_2[/tex]
Therefore, the weight of an object at the poles, W₁, is more than the weight of the object at the equator, W₂

A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of the loop in which the plane is flying?
Answer:
The radius of the curve is 9,183.67 m.
Explanation:
Given;
velocity of the jet plane, v = 600 m/s
acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²
The radius of the curve is calculated from centripetal acceleration formula as given below;
[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]
Therefore, the radius of the curve is 9,183.67 m.

FALSE - Watt is the standard metric unit of power; Joule is the standard metric unit of energy. ... TRUE - A kg•m2/s2 is a mass unit times a speed squared unit, making it a ...
(a) If a person can jump a maximum horizontal distance (by using a 45° projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g 5 9.80 m/s2 ? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
Answer:
See explanation
Explanation:
Range of a projectile is given by; U^2sin2θ/g
When θ = 45°
The maximum range is obtained as;
Rmax = U^2/g
Maximum range on earth = RME = U^2/g
Maximum range in the moon= RMM =U^2/g/6
Maximum range in Mars = RMMA = U^2/0.38g
a)
RME/RMM = U^2/g/U^2/g/6
RME/RMM = 6
But RME = 3 m
RMM = 3 * 6 = 18 m
b)
RME/RMMA =U^2/g/U^2/0.38g
RME/RMMA = 1/0.38
But RME = 3 m
RMMA = 3/0.38
RMMA = 7.9 m
A rocket is fired at 60 to the horizontal with an initial speed of 200m5 calculate it time of flight and it range on the horizontal plane
Answer:
See answer below
Explanation:
In order to do this, we just need to apply the expression to determine the time of flight. This is given by:
t = 2 V₀ Sinθ / g (1)
We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:
t = 2 * 200 Sin60° / 9.8
t = 35.348 sNow that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:
X = V * t (2)
We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:
X = 200 cos60° * 35.348
X = 100 * 35.348
X = 3534.8 mHope this helps

A man started at his house and went to the post office, then to the pet store, and finally home again. What is the average velocity if this trip took three hours?
Explain how you arrived at your answer.
Answer:
0
Explanation:
Defining velocity :
Velocity is a vector which is the ratio of a person's total displacement with time.
Displacement, in simple terms refers to the distance between an individual's initial position to his final position.
Man's initial position = House
After all his navigation and points covered irrespective of the distance ;
Final position = House
Hence, we can conclude that the man's Displacement is ;
Final position - Initial position = 0
Hence,
Velocity = Displacement / time taken
Velocity = 0 / 3
Velocity = 0
Two objects of mass 5 kg and 8 kg at rest F1 and F2 meters force applied on both the boxes respectively If the speed of both the objects after 5 sec become 16m/s and 15m/s respectively find the value of F1 and F2?
Answer:
F1 = 16 N and F2 = 24 N
Explanation:
Formula used => F = m×a and v-u= at
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
FOR 1ST BLOCK
16= <math> F1/5 </math> × 5 ==> F1 = 16 N
FOR 2ND BLOCK
15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

what causes lightning?
Answer:
cause by imbalances between stroms cloud and grounds , or within the cloud themselves.
Explanation:
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
The positive and negative charges grow large enough, a giant spark lightning, occurs between the two charges within the cloud.
What is lightning?The naturally occurring electrostatic discharge with high voltage for short duration from the cloud to the ground or within the cloud. The lightning can be seen by a flash of light that could be followed by the strong sound. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground or within the clouds. In the starting stages air acts as an insulator, but after the charges build up with the charges in the ground and cloud there will be the rapid form of electricity causes lightning. These lightning were in the color of bluish white.
Thus, the charges discharging naturally causes lightning.

An airplane traveling at 201 m/s makes a turn. What is the smallest radius of the circular path (in km) that the pilot can make and keep the centripetal acceleration under 5.0 m/s2 ?
Answer:
the smallest radius of the circular path is 8.1 km
Explanation:
The computation of the smallest radius of the circular path is given below:
Given that
V = Velocity = 201 m/s
a_c = acceleration = 5 m/s^2
radius = ?
As we know that
a_c = V^2 ÷ r
5 = 201^2 ÷ r
r = 201^2 ÷ 5
= 8,080.2 g
= 8.1 km
Hence, the smallest radius of the circular path is 8.1 km
