A labourer carries a load of 500N to a distance of 100m
The work done is??
Explanation:
Hey there!
Given;
Load = 500N
Distance= 100m
Acceleration due to gravity= 9.8m/s^2.
We know;
Work done = F * d
W = (500*9.8)*100
W= 490000J
Therefore, the work done by the carrier is 490000J.

Answer:
Siberia
Explanation:
The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050 mbar with record highs close to 1085 mbar.
NOTE: mbar = Millibar, the unit of air pressure in the metric system, commonly used in meteorology, equal to 100 pascals, 1,000 dynes per square cm (about 0.0145 pounds per square inch), or slightly less than one-thousandth of a standard atmosphere.

The direction of the sum of vectors A and B is approximately 22.9 degrees north of east.
To find the direction of the sum of vectors A and B, we can use trigonometry to determine the angle with respect to the positive x-axis (east direction). The given vectors A and B have magnitudes and directions as follows:
Vector A: Magnitude = 9.66 m, Direction = East
Vector B: Magnitude = 12.0 m, Direction = Northwest (which is 45 degrees north of west)
To find the resultant vector's direction, we need to add the angles of the two vectors. The angle between the positive x-axis and vector A is 0 degrees (east direction), and the angle between the positive x-axis and vector B is 45 degrees (northwest direction). Therefore, the angle between vector A and the resultant vector is 0 degrees, and the angle between vector B and the resultant vector is 45 degrees.
To find the angle of the resultant vector with respect to the positive x-axis (east direction), we can use the tangent function:
Tan(Angle)= Opposite/Adjacent = Magnitude of Vector A/Magnitude of Vector B
Taking the inverse tangent (arctan) of both sides:
Angle = arctan (9.66/12.0)≈22.9 degrees
So, the direction of the sum of vectors A and B is approximately 22.9 degrees north of east.

A. Rocket 3
B. Rocket 1
C. Rocket 4
D. Rocket 2
In the given four models of rockets, the rocket with the highest acceleration is rocket 2.
Acceleration of the rocketsAcceleration is the rate of change of velocity with time. The acceleration of the rockets can also be determined from Newton's second law of motion with the applied force and mass of each rocket as shown below;
F = ma
where;
F is the applied forcem is the massa is the accelerationa = F/m
Rocket 1a = 120/4.25
a = 28.24 m/s²
Rocket 2a = 120/3.25
a = 36.92 m/s²
Rocket 3a = 120/5.5

How do you determine the effect of initial speed on the horizontal distance traveled by a projectile?
x(t)=voₓ.t = vo cos α.t
the greater the initial speed, the further the distance obtained
The horizontal distance traveled by a projectile (also known as the range of the projectile) is determined by the initial speed of the projectile, as well as other factors such as the angle at which it is launched and the gravitational acceleration acting on it.
What is a projectile?A projectile is an object that is projected into the air and follows a parabolic path under the influence of gravity. Examples of projectiles include balls thrown or kicked in sports, bullets fired from guns, and rocks or other objects that are thrown or dropped.
To determine the effect of the initial speed on the horizontal distance traveled by a projectile, you can use the following formula:
[tex]Range = (Initial speed)^2 * sin(2 * Launch angle) / gravitational acceleration[/tex]
This formula shows that the range of a projectile is directly proportional to the initial speed of the projectile squared, and is also affected by the launch angle and gravitational acceleration.

Explanation:Got it correct
For a substance to change from a liquid to a solid, the particles must lose enough of their kinetic energy so that the attractions between them hold in place as they vibrate. Thus, the correct option is C.
What is Kinetic energy?Kinetic energy is the energy which an object has because of its motion. If we want to accelerate an object, then it is required to apply a certain amount of force. Applying a force requires us to perform work. After work has been done on the object, then the energy has been transferred to the object, and the object will be moving with a new constant speed and no acceleration.

Before a diver jumps off of a diving board she has 7500J of Gravitational energy. What is the maximum amount of kinetic energy the diver will have just before she hits the water?
Answer:
i think it was 7500 j . beacause sometimes we can say that U=K after that thing is near the floor
The maximum amount of kinetic energy the diver will have just before she hits the water will be the same as the gravitational potential energy before take-off. Maximum kinetic energy is also 7500Joules
Gravitational energy is the energy possessed by an object by virtue of its position.
It is expressed according to the formula:
GPE = mgh
m is the mass of the object
g is the acceleration due to gravity
h is the height
If a diver has Gravitational energy of 7500Joules before the diver jumps off, the maximum amount of kinetic energy the diver will have just before she hits the water will be the same as the gravitational potential energy before take-off.
GPE = kinetic energy at the bottom = 7500Joules

Explanation:
I hope my answer helped <3 Have a nice day
The equation for the speed of the wave is v = λ × f. The speed of a wave depends on wavelength and frequency.
The rate at which a wave moves across a medium is referred to as its speed. It displays the speed at which the wave's disruption or energy spreads. The characteristics of the medium a wave travels through affect its speed.
The equation for the wave's speed (v) for a mechanical wave, such as one moving via a string or a spring, is as follows:
v = λ × f
Here:
v = speed of the wave
λ = wavelength of the wave
f = frequency of the wave
