Answer: 17.5N
Explanation:
Given that,
spring constant (k) = 70N/m
Original length (lo) = 40 cm
New length (ln) = 15 cm
extension of spring (e) = new length - original length
i.e e = ln - lo
e = 15 cm - 40 cm
e = -25cm (the negative sign is negligible, just the same magnitude matters)
So, convert 25cm to metres
If 100cm = 1m
25cm = 25/100 = 0.25m
(Note that how hard the spring push refers to the Force, hence, find force.)
Now, apply the Hooke law (F = ke)
Force = spring constant x extension
F = 70N/m x 0.25m
F = 17.5N
Thus, the spring push with a force of 17.5N when compressed.
Answer:
an orange fringe at 0°, yellow fringes at ±50° and red fringes farther out.
Explanation:
In the visible spectrum- red to violet, red has the highest wavelength.
The maximum internsity for diffraction grating is given by,
Sinθ = mλ/d
It is concluded that the angle of diffraction increases with increase in wavelength'λ' . So, red fringe will be farthest from the center, orange light will be at the center and yellow fringe will be at 50°.
Therefore, The new pattern consists of : an orange fringe at 0°, yellow fringes at ±50° and red fringes farther out.
Displacement is the total space between point a and b. For example, If I walk 3 times North, 6 times East, and 7 times North, what is the displacement? The answer is 10 because when I walked East there was on object blocking my way.

Answer: The squishy ball
Explanation:
The squishy ball experiences a larger force due to its soft nature. The force of the squishy ball cannot overcome the concrete cube due to the weight of the concrete and as such the weight of the concrete cube will overcome the force exerted on it by the squishy ball making the ball to experience much larger force.
