Answer:
Yes, in case of uniform velocity
Explanation:
This is the case of uniform velocity. If a body covers equal displacement in equal intervals of time, then the velocity of a body is said to be ‘Uniform Velocity’. It meas that the velocity of a body remains constant during the motion and it does not change.
Since, acceleration is defined as the rate of change of velocity.
Therefore, if there is no change in velocity or in other words the change in velocity is zero, then the acceleration is also zero.
a = ΔV/t = 0/t
a = 0 m/s²
So, the acceleration of the body is 0 m/s², but it has a uniform velocity
<u>Hence, it is possible for an object that, object with zero acceleration have velocity, which is the case case of uniform velocity.</u>
Answer:a number without a decimal are generally not significant. Isotopes are atoms of same element which have the same atomic number but different number of neutrons. Isotopes of elements are represented in the following way: In an atom, the number of protons is equal to its atomic number.. An atom of an element is neutral in nature so atom contains the same number of protons and electrons.

you have to provide mass to get acceleration
as Newton's 2nd law, force=mass×accln
now,here force toward D is 100N,if it hav mass m
then accln will be 100/m
Answer:
T = 1.73 kg
Explanation:
Let's use Newton's second law for this balance problem
We draw a coordinate system with the x axis parallel to the plane and the Y axis perpendicular
The only force we have to lay down is the weight (W)
Wx = W sin θ
Wy = W cos θ
Wx = 2.0 ain 60
Wx = 1.73 kg
Wy = 2.0 cos 60
Wy = 1.0 kg
Y Axis
N-Wy = 0
X axis
T- Wx = 0
T = Wx
T = 1.73 kg
