Answer:
Change in velocity and direction over a specific period of time.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate the acceleration of an object.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Hence, the types of changes in motion that cause acceleration is a change in velocity and direction over a specific period of time.
Answer:
Explanation:
Angle of dip = 56° , magnetic field strength = 50μT
Vertical component = 50 x sin 56 = 41.45 μT
Horizontal component = 50 cos 56 = 27.96μT
New field is added in vertical downwards direction to increase the vertical component so as to increase the angle of dip . Let this field be B
total vertical field = B + 41.45
Horizontal component = 27.96
dip angle be θ
tanθ = vertical component / horizontal component
tan62 = B + 41.45 / 27.96
1.88 = B + 41.45 / 27.96
52.58 = B + 41.45
B = 11.13 μT
Since magnetic field has to be added , current should be clockwise when looked from above.
Answer:
Part A:
Time taken by the snake to reach its top speed is 1.28571 sec.
Part B:
Snake travels 2.0828 m in that time
Part C:
Mongoose have a chance to catch the black mamba
Explanation:
Part A:
According to first equation of motion:
v_f is top speed
v_i is initial or minimum speed
t is time
a is acceleration
Time taken by the snake to reach its top speed is 1.28571 sec
Part B:
According to Second equation of motion:
v_i=0
Snake travels 2.0828 m in that time
Part C:
Distance covered by black mamba is 2.0828 m which is less than its length 3.12 m
2.0828 m<3.12 m
Mongoose have a chance to catch the black mamba
<h3>Answer: any path that allows electrons to flow</h3>
An electrical circuit is a path in which electrons from a voltage or current source flow. ... The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".
