Gradually increasing resistance, increasing repetition, increasing sets are examples of which principle?
Answer:
Resistance training.
Explanation:
Resistance training is based on the principle of gradually increasing resistance, increasing repetition and increasing sets to acquire resistance. Resistance training refers to those physical exercises which are designed and done to improve strength and endurance of the body. Resistance training uses the principle of repetition of a particular exercise in order to attain strength as well as resistance against diseases.
A man speeding at 40m/s decides to outrun the cops and starts to accelerate at a rate of 2.5m/s² for 12 seconds. How far did he travel in this time?
Answer:
The distance traveled by the man during the acceleration is 1186.32 meters
Explanation:
The initial velocity of the man = 40 m/s
The added acceleration rate of the man to outrun = 2.5 m/s²
The time of acceleration = 12 seconds
The relevant kinematic equation of motion is given as follows;
s = u·t + 1/2·a·t²
Where;
u = The initial velocity of the car the man is driving = 40 m/s
t = The time of travel during acceleration of the car the man is driving = 12 seconds
a = The acceleration by the man to outrun the cops = 2.5 m/s²
s = The distance traveled by the man during the acceleration
Substituting, gives;
s = 40 × 12 + 1/2 × 9.81 × 12² = 1186.32
The distance traveled by the man during the acceleration = s = 1186.32 m.

each one around a bete beten places alive betties in direct sunlight and measures the temperature of the water in each clean hout
what is the independent variable in this exermet
the temperature of the water
the outside temperature
the color of the con
Answer:
This question is unclear but the answer is:
the color of the con
Explanation:
In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter to achieve a measurable response.
In this experiment which involves a student that notices that wearing care colors insight makes him feel warmer se. He decides to conduct an experiment by manipulating the colors of the cares, hence, the color of the con is the independent variable.
A ball of mass 0.12kg is hit by a tennis player. The velocity of the ball changes from 0m/ s to 5.0m/s in 0.60s. What is the average resultant force acting on the ball while it is being hit?
A 1.0N B 2.5N C 3.6N D 8.3N
(Please add explanation)
Answer:
A. 1.0NExplanation:
According to Newton's second law
F = ma
m is the mass = 0.12kg
a is the acceleration = v-u/t
a = 5-0/0.6
a = 5/0.6
a = 8.333m/s²
Get the force
F = 0.12 * 8.333
F = 1.0N
Hence the average resultant force acting on the ball while it is being hit is 1.0N

Where would you find convergent and divergent plate boundaries relative to
convection currents in the mantle?
Answer:
When two tectonic plates meet, we get a “plate boundary.” There are three major types of plate boundaries, each associated with the formation of a variety of geologic features.
Explanation:
When the plates meet at the boundaries the convergent boundaries lie at the collision of two plates and the divergent lies near mid-oceanic ridges.
What are plate boundaries?The earth plate tectonics are divided into the three types of plates as convergent which is the destruction of crust and are found where the heavy and light plate comes and colloid with each other submerging the heavier plate into the mantel.
The divergent ones found near the mid-oceanic ridges are the formation of a new plate as the plates diverge away from the ridges.

How are speed and velocity similar?
Answer:
Speed and velocity are related in much the same way that distance and displacement are related. Speed is a scalar and velocity is a vector.

Electric circuits provide a path for ___ to flow.
protons
matter
electrons
energy
Electric circuits provide a path for electrons.
The passage of electrons is facilitated by electric circuits.
An electric circuit resembles a roadway consisting of wires over which electrons are transferred.
The force that causes the electrons to travel comes from a battery or another power source. To allow electrons to travel from the source of power to the gadget and back, wires must be run from the source of electricity to the gadget and back.So, Option "C" is the correct answer to the following question.

Which one hits the ground first, a
bullet dropped from a height, or a
bullet fired simultaneously from
the same height?
Answer:
A bullet fired simultaneously from the same height
Explanation:
It will reach the ground first because a greater force is being acted upon it. The first option is only acted on by gravity
1. The geologic time scale divides time into years and centuries, true or false
Answer:
The answer is "False"
Explanation:
The geologic time scale is the "schedule" for occasions in Earth history. It partitions time into named units of unique time called in descending order of duration "eons, eras, periods, epochs, and ages". The specification of those geologic time units depends on stratigraphy, which is the relationship and order of rock layers. The fossil structures that happen in the stones, nonetheless, give the central methods for setting up a geologic time scale, with the circumstance of the development and vanishing of far and wide species from the fossil record being used to outline the beginnings and endings of ages,, periods, and different stretches.
Geologic time is the broad time period involved by the geologic history of Earth. Formal geologic time starts toward the beginning of the Archean Eon (4.0 billion to 2.5 billion years back) and proceeds to the current day.
A car is traveling with 90km/hr and another car with 20m/s in opposite direction. Calculate the relative velocity.
Answer:
Vba = -20 m/s - 25 m/s = -45 m/s
Vab = 25 m/s + 20 m/s = 45 m/s
Explanation:
Relative Velocity
The relative velocity of object B with respect to object A (Vba) measures the velocity of B in the rest frame of object A.
It's calculated as:
Vba = Vb - Va
The velocity of car B is Vb=-20 m/s and the velocity of car A is Va=90 Km/h.
Converting Va to m/s:
Va = 90 Km/h * 1000/3600 = 25 m/s
Thus, the relative velocity of B with respect to A is:
Vba = -20 m/s - 25 m/s = -45 m/s
And the relative velocity of A with respect to B is:
Vab = 25 m/s + 20 m/s = 45 m/s
what is the velocity for an object at rest?
Answer:
e
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
Answer:
If an object is at rest, it has no velocity - its velocity is zero. More precisely, since velocity is a vector, in this case the velocity would be the null vector.

A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 41.5-gram mass is attached at the 28.5-cm mark, the fulcrum must be moved to the 39.2-cm mark for balance. What is the mass of the meter stick
Answer:
The value is [tex]M = 42.3 \ kg[/tex]
Explanation:
From the question we are told that
The first position of the fulcrum is x = 49.7 cm
The mass attached is [tex]m = 41.5 \ g[/tex]
The position of the attachment is [tex]x_1 = 28.5 \ cm[/tex]
The second position of the fulcrum is [tex]x_2 = 39.2 \ cm[/tex]
Generally the sum of clockwise torque = sum of anti - clockwise torque
So
[tex]CWT = m (x_2 - x_1)[/tex]
Here CWT stands for clockwise torque
[tex]ACWT = M ( x - x_2)[/tex]
So
[tex]m (x_2 - x_1) = M ( x - x_2)[/tex]
=> [tex]41.5 (39.2 - 28.5 ) = M ( 49.7 -39.2 )[/tex]
=> [tex]M = 42.3 \ kg[/tex]

The mass of Saturn is 5.69 · 10^26 kg. Calculate the gravitational field that it exerts on its Mimas satellite, knowing that the mean radius of its orbit is 186,000 km. Data: G = 6.67 · 10^-11 N · m2 · kg ^-2.
Answer:
The gravitational field that Saturn exerts on the satellite, Mimas is approximately 1.097 m/s²
Explanation:
The given mass of Saturn = 5.69 × 10²⁶ kg
The radius of the orbit of the Mimas satellite = 186,000 km
The gravitational constant, G = 6.67 × 10⁻¹¹ N·m²·kg⁻²
From Newton's law of gravitation, we have;
[tex]The \ gravitational \ field =G\times \dfrac{M}{R^{2}} = 6.67 \times 10^{-11} \times \dfrac{5.59 \times 10^{26}}{(186,000,000)^2} \approx 1.097[/tex]
6.67 × 10⁻¹¹ *(5.69 × 10²⁶)/(186,000,000)²
The gravitational field that Saturn exerts on the satellite, Mimas ≈ 1.097 m/s².
