Helllo fellow brainly student!
The best answer is A- with a screen.
This is the best choice because
what this means is to use a sifter.
A sifter is a screen like tool you can
Use to make the lumps disappear from
Flour, sugar, and other cooking ingredients.
Hope this helps! Have a jolly evening.
Answer:
In physics, mass–energy equivalence is the principle that anything having mass has an equivalent amount of energy and vice ve
Answer:
u = 7.74 m/s and t = 1.82 s
Explanation:
Given that,
Harold threw a baseball 3 meters.
Harold is 2 meters tall.
The vertical distance = 3m
The final velocity at the maximum height is 0.
Let u is the initial velocity of the baseball. Using the first equation of motion to find it as follows :
Here, a = -g
He has thrown it with the speed of 7.74 m/s
Let t is the time taken by the ball to fall on the ground.
Harold is 2 meters tall. Using second equation of motion to find it.
u = -7.74 (as downward direction is taken as positive)
Hence, this is the required solution.
Answer:
Yes.
Explanation:
Yes Light has inertia, since inertia is in units of mass.
Answer:
14.56 N
Explanation:
According to Newton's second law of motion,
The force acting on a body is equal to the product of its mass and acceleration acting on it.
Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.
Here, acceleration due to gravity on planet A is m/s² and mass of an object on it is kg.
So, weight of an object, , on planet A is given as,
