Explanation:
of the following states of motion, the one which requires balanced forces is:
A: a decrease in speed in a straight line
B: an increase in speed in a straight line
C: constant speed in a straight line
D: a change in the direction of the motion
A balanced force is required for a change in the direction of the motion.
What is a force?According to Newton's second law of motion, the force applied to a body is directly proportional to the product of mass and acceleration of the body.
Balanced forces
Balanced forces are those that are opposite in direction and equal in size. When forces are balanced there is no change in direction.
Thus, when there is change in direction, a balance force can be applied to cancel the change in direction of motion.

Explanation:
you measure temperature in degrees celsius using a thermometer. Thermal energy is measured in joules. A larger volume of water will take longer to heat up but will store more energy than the smaller object. However, a smaller object will lose it's heat faster than a larger object. A cup of tea has less thermal energy than a swimming pool.

hello I wanna know what is the Newton first is also called the law
Answer:
What is another name for the first law of motion? Why is it given that name? Law of inertia. Page 2. It is given that name because inertia is the tendency of an object to resist any change in its motion until an unbalanced force acts on it.

If it is 9 am in San Francisco, is it also 9 am in New York? Why or why not?
If it is 9 am in San Francisco, then there will be 12pm in New York. it happens because of spin rotation of our earth.
What is Clock ?A clock or a timepiece is a device used to measure time. The clock is one of the oldest human inventions. It has three hands moves in the circle. one is second hand, which show seconds. Second hand shows hours and third hand which is smaller than other shows hours.
San Francisco, California is 3 hours behind New York. There will be 12pm in New York when it is 9 am in San Francisco. Day and night happens because of our earth is spinning about itself. when we take a football in the dark room and illuminated it by the torch, then one side of the ball gets illuminated and other side of the ball gets dark due to shadow of its own, Same happens with our earth. it this case torch is our sun and earth is our football. The people who are on the darker side they are in the night and who are in the light side they are in the morning.
Morning starts where edge of the light is. Tme changes with lateral distance on the earth. The points which is on same longitude have same time. There is lateral displacement from San Francisco to New York. Therefore there is time lag between them.
Hence there is time lag.

The acceleration due to gravity is 9.81 m/s2, towards the Earth. Rain falling from an altitude of 9,000 m would fall for about 1.5 minutes before hitting the ground (ignoring air resistance). What would be the final speed of a raindrop by the time it reaches the ground?
Answer:
the final speed of the rain is 541 m/s.
Explanation:
Given;
acceleration due to gravity, g = 9.81 m/s²
height of fall of the rain, h = 9,000 m
time of the rain fall, t = 1.5 minutes = 90 s
Determine the initial velocity of the rain, as follows;
[tex]h = ut + \frac{1}{2} gt^2\\\\9000 = 90u + \frac{1}{2} (9.8)(90)^2\\\\9000 = 90u + 39690\\\\90u = -30690\\\\u = \frac{-30690}{90} \\\\u = -341 \ m/s[/tex]
The final speed of the rain is calculated as;
[tex]v^2 = u^2 + 2gh\\\\v^2 = (-341)^2 + 2(9.8\times 9000)\\\\v^2 = 292681\\\\v = \sqrt{292681} \\\\v = 541 \ m/s[/tex]
Therefore, the final speed of the rain is 541 m/s.
Answer:
The magnitude of the final speed of a raindrop by the time it reaches the ground will be 541.45 m/s.
Explanation:
The final speed of the raindrop can be found using the following equation:
[tex] v_{f} = v_{0} - gt [/tex]
Where:
[tex]v_{f}[/tex]: is the final speed =?
[tex]v_{0}[/tex]: is the initial speed
g: is the acceleration due to gravity = 9.81 m/s²
t: is the time = 1.5 min
First, we need to find the initial speed:
[tex] y_{f} = y_{0} + v_{0}t - \frac{1}{2}gt^{2} [/tex]
Where:
[tex]y_{f}[/tex]: is the final height = 0
[tex]y_{0}[/tex]: is the initial height = 9000 m
Hence, the initial speed is:
[tex] v_{0} = \frac{y_{f} - y_{0} + \frac{1}{2}gt^{2}}{t} = \frac{0 - 9000 m + \frac{1}{2}9.81 m/s^{2}*(90 s)^{2}}{90 s} = 341.45 m/s [/tex]
Hence, the final speed is:
[tex] v_{f} = v_{0} - gt = 341.45 m/s - 9.81 m/s^{2}*90 s = -541.45 m/s [/tex]
Therefore, the magnitude of the final speed of a raindrop by the time it reaches the ground will be 541.45 m/s.

The athlet at point A runs 150m east, then 70m west and then 100 east
Determine the resultant displacement of the athlete relative to point A
Answer:
180m to the east
Explanation:
Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.
point A runs 150m east,
70m west
100m east
150m
--------------------------------------------------------→
70m
←---------------------
100m

please thank the person above me though, they deserve it.
These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.
How do snakes detect?With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.
They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.

A squirrel starts at rest and accelerates at 2.3 m/s^2 for 5.22 seconds. What is it's final velocity?
Please provide the variable, number, and unit e.g., a= 1.34 m/s^2
Answer:
12.259 m/s
Explanation:
An object starting at rest and accelerating at a constant acceleration a for t seconds has a velocity of
[tex]v=at[/tex]
If we substitute in the values a = 2.3 m/s² and t = 5.22 s, we get a velocity of

Mass of worker = 60kg
g = 9.81m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body is the energy due to the position of the body.
It is expressed as:
G.P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height = 45 + 10 = 55m
G.P.E = 60 x 9.8 x 55 = 32340J
