The radar device determines the vehicle's instantaneous speed.
I would argue that the purpose of the device is not to determine
whether individuals are driving safely. They only determine whether
individuals are driving within legal speed limits. There's much more
to 'safe' driving than that, but the radar gun can't detect it.
Answer:
The essential characteristics of an object in equilibrium is acceleration of the object must be zero.
Explanation:
Equilibrium: An object acted upon by several forces is said to be in equilibrium if it does no it moves or rotate. Equilibrium can be defined as the state of stability of an object.
Condition for equilibrium
(i) The resultant force acting on the object must me equal to zero.
(ii) The sum of moment acting on the object must be equal to zero.
But.
F = ma..................... Equation 1
Where F = net force , m = mass, a = acceleration.
from the equation above,
For F = 0 N, a must be equal to zero.
<em>From the above, the essential characteristics of an object in equilibrium is acceleration must be zero</em>
<span>There is only one thing that you must keep in mind, and that is that the ball hitch and coupler for towing have to be the same size. If not, then you can create a problem which can in turn result with damage to you and your boat and you would have to spend a lot of money to fix things or get a new boat.</span>
Answer:
khoảng cách = 8km / h
Explanation:
khoảng cách = tốc độ / thời gian
khoảng cách = 12/40
khoảng cách = 8km / h
