Answer:
It’s mass would be the same
Explanation:
Mass and weight are often used interchangeably in everyday conversation. For example, our medical records often show our weight in kilograms but never in the correct units of newtons. In physics, however, there is an important distinction. Weight is the pull of Earth on an object. It depends on the distance from the center of Earth. Unlike weight, mass does not vary with location. The mass of an object is the same on Earth, in orbit, or on the surface of the Moon.
Answer:
<h2>132 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 66 × 2
We have the final answer as
<h3>132 N</h3>
Hope this helps you
Answer:
15Ns
Explanation:
Given parameters:
Mass of the object = 10kg
Force impact = 5N
Time of action = 3s
Unknown:
Impulse applied on the object = ?
Solution:
Impulse is the force that acts on object within a period of time.
Mathematically;
Impulse = Force x time
Now insert the parameters and solve;
Impulse = 5 x 3 = 15Ns
Answer:
Explanation:
s(t) = 5t³-2t²+9
Instantaneous velocity v = ds / dt
v = ds/dt = 15t²-4t
Putting t = 7
v = 15 x 7² - 4 x 7
= 707
Instantaneous velocity at t = 7
is 707 unit .
ρ=2.5⋅g⋅cm3............
Explanation:
ρ=Mass/Volume=5⋅g2⋅cm3,
and thus typically it has the units g⋅mL−1 or g⋅cm−3.
Here, mass=5⋅g, and volume=2⋅m3.
Their quotient is the density as shown. And this could be any solid material (generally solids are denser than liquids). You will have to look up tables of densities for common materials.
