Answer:
200N
Explanation:
mass = 20 kg
acceleration = 10 m/s^2
Force = mass * acceleration
= 20 *10
= 200 N

A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. ... This means that some individuals would survive and be able to reproduce and generate more offspring.
Moving a spring toy up and down will create what kind of disturbance?
parallel to the wave motion
in a circular motion
in the same direction as the wave motion
perpedicular to the wave motion
Answer:
Perpindicular to the wave motion.
Explanation:
Moving a spring toy up and down will create a disturbance in the same direction as the wave motion.
We can classify waves by the direction of wave motion in which case waves are classified into;
Transverse wavesLongitudinal wavesLongitudinal waves are waves in which the direction of disturbance is in the same direction as the wave motion. The wave along a spring is a longitudinal wave therefore; moving a spring toy up and down will create a disturbance in the same direction as the wave motion.

What work is done when a person lifts a 1.6 kg package and places it on a shelf 2.4m high?
Answer:
Explanation:
Work is the dot product of force and distance
[tex]W = F*d=Fd*\cos(theta)[/tex]
The only force acting on this box is the force of gravity (weight) which is mass*gravity
F = (1.6)(9.8) = 15.68N
The angle is the angle between the force and distance. In this case it is zero, therefore cos(Ф) = 1
[tex]W=15.68*2.4=37.6J[/tex]

Why does the North star not move but the other stars move
Answer:
it's the star in the center of the star field
Explanation:
Why Doesn't Polaris Move? Polaris is very distant from Earth, and located in a position very near Earth's north celestial pole. ... Polaris is the star in the center of the star field; it shows essentially no movement. Earth's axis points almost directly to Polaris, so this star is observed to show the least movement

Determine the stopping location of the prize wheel. At this moment it is centered on the number 5. It is spinning with an energy of 6.19 J. It is slowing at a rate of 1.800 rad/s/s.
The disk is made from a wood with a density of 478.0 kg/m^3. The disk is 29.0 mm thick and has a radius of 33.0 cm.
Predict the angular displacement it will go through and predict the number on which the wheel will stop. To be safe, you will also get one number the right and to the left of the number you chose.
The wheel will spin clockwise. The wheel goes from 1 to 36.

Why did you need to heat the water to make the nectar?
A. Heating the water increases the solubility of the sugar.
B. Heating the water decreases the melting point of the sugar.
C. Heating the water increases the boiling point of the sugar.
D. Heating the water increases the particle motion of the sugar.
Answer:
D
Explanation:
Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.

An object moving with a speed of 35 m/a and has a kinetic energy of 1500j, what is the mass of the object
Explanation:
Speed or velocity (V) = 35 m/s
Kinetic energy (K. E) = 1500 Joule
mass (m) = ?
We know
K.E = 1/2 * m * v²
1500 = 1/2 * m * 35²
1500 * 2 = 1225m
m = 3000 / 1225
m = 2.45 kg
The mass of the object is 2.45 kg

A man driving a car sees a deer crossing the road and brakes the car with a force of 100 N. The car stops after traveling 5m. What is the work done on the car?
Answer:
Workdone = 500Nm
Explanation:
Given the following data;
Force = 100N
Distance = 5m
To find the workdone;
Workdone is given by the formula;
[tex] Workdone = force * distance[/tex]
Substituting into the equation, we have
[tex] Workdone = 100 * 5 [/tex]
Workdone = 500Nm
A spring is compressed between two blocks, one with a mass of 2 kg and the other with a mass of 3 kg. If the 2 kg block has an average acceleration of 6 m/s^2 when the spring acts on it, what will be the average acceleration of the 3 kg block???
Answer:
2=6
3=9
Explanation:
I think this is right I'm not sure but I have done problems like this and did based on what I remember.
The average acceleration of the 3 kg block is 4 m/s².
The given parameters;
mass of first block = 2 kgmass of second block = 3 kgacceleration of the first block, = 6 m/s/sAccording to Newton's third law of motion, action and reaction are equal and opposite.
The force exerted on both blocks are equal and opposite.
[tex]F = ma\\\\m_1 a_1 = m_2a_2\\\\a_2 = \frac{m_1 a_1}{m_2}\\\\a _2 = \frac{2\times 6}{3} \\\\a_2 = 4 \ m/s^2[/tex]
Thus, the average acceleration of the 3 kg block is 4 m/s².

A construction worker pushes a wheelbarrow 15 m with a horizontal force of 17 N. How much work is done by the worker on the object?
Answer:
The work done by the worker on the object is 255 J
Explanation:
Work is defined as the force that is applied on a body to move it from one point to another.
When a net force is applied to the body or a system and this produces displacement, then that force is said to perform mechanical work. This work can be positive if the system gains energy or negative if the system loses energy.
In the International System of Units, work is measured in Joule. Joule is equivalent to Newton per meter.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that travels the point or the object that moves.
In this case, the angle between the force and the displacement is 0 degrees. Then the cosine of 0 degrees will have a value of one. So work is calculated as the multiplication between force and distance:
W= 17 N* 15 m
Solving:
W= 255 J
The work done by the worker on the object is 255 J
Naoki's bicycle has a mass of 9 kg. If Naoki sits on her bicycle and starts pedaling with a force of 107.2 N, causing an acceleration of 1.6 m/s2, what is Naoki's mass?
A.
69 kg
B.
58 kg
C.
67 kg
D.
14 kg
PLZ HELP ME........thank you
Answer:
Explanation:
F = ma
m = F/a
m = 107.2/1.6 = 67 kg
so Naoki's mass must be the total mass - mass of the bike
so her mass is 67 - 9 = 58 kg...B
