Answer:
The correct options are (b) and (d)
There are two the same and correct options.
The name of the shape on the right is because it is the pre-image of the shape on the left.
Explanation:
A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
A pre-image or is the two-dimensional shape before any transformation.
The image is the figure after transformation.
The five transformation's factors are:
Shear, Rotation, Reflection, Translation and Dilation.
Miosis is simair to mitosis that create gamtetes and zyotes together
Answer: 4.9 N
Explanation:
Weight is the force that gravity exerts on matter and changes depending on where the body is located. This means, the weight of an object on Earth will not be the same as the weight of the same object on the Moon or on Mars.
Well, in the case of Galileo, he performed his experiment on Earth. Hence, the acceleration due gravity is .
In addition, weight is mathematically expressed as:
Where is the mass of the ball
Solving the equation:
This is the weight of the ball
Answer:
Part A
it would take 6 sec
it would take 3 sec
Explanation:
We are told that the power supplied to the wheel is constant which means that the sport car is gaining energy i.e
Hence if power is constantly supplied energy constantly increase
From the formula of the Kinetic energy
we can see that as the speed doubles from 29 mph to 58 mph the energy needed is = 4 times of the energy from the formula
Also the time needed would also be 4 times because energy i directly proportional to time
Hence to reach 58mph the time that it would take is
=
We are told that the ground pushes the car with a constant force and
F = ma
this means that the acceleration is also constant
now from newtons law
v = u +at
Looking at it we see that final velocity is directly proportional with time
hence it would take twice the time to reach twice the final velocity
Time to reach 58mph = 3 s
since time to reach 29 mph() =( )1.5 s
