Physics

1 answer:

Artemon [7]3 years ago

7 0

Answer:

Explanation:

Dimensions of current = A

Dimensions of time = T

Current = Charge / time

Therefore Charge = Current × time

[Charge] = [Current] × [time]

= AT

Which activity directly converts energy from the Sun into chemical energy?

umka21 [38]

The biological process that directly converts energy from the Sun into chemical energy would be Photosynthesis. It is a process carried out by autotrophic organisms which are predominantly plants and other photosynthetic bacteria.

A heavy boy and a lightweight girl are balanced on a massless seesaw. If they both move forward so that they are one-half their

Yuki888 [10]

Answer:

The system is still balanced

Explanation:

If we suppose that the boy weights M and the girl m, and are balanced at distances L1 and L2 from the pivot point respectively, thy will be balanced if the resultant torque of all the farces from the pivot pint is cero:

(1) $T=M*L1-m*L2=0$

now they moved to distances (L1)/2 and (L2)/2, the resultant torque will be:

(2) $T=M*(L1)/2-m*(L2)/2$

1/2 can be taken out as a common factor:

(3) $T=(M*L1-m*L2)*1/2$

As the the inside of the parenthesis equals equation (1) that equals zero, hte whole equiation equals zero:

(3) $T=(0)*1/2=0$

So the system is still balanced

A concrete block is hung from an ideal spring that has a force constant of 100 N/m . The spring stretches 0.129 m .A- What is th

madam [21]

Answer:

1.31498 kg

0.72050 s

Explanation:

m = Mass of block

g = Acceleration due to gravity = 9.81 m/s²

k = Spring constant = 100 N/M

x = Displacement = 0.129 m

The force balance is

$mg=kx\\\Rightarrow m=\dfrac{kx}{g}\\\Rightarrow m=\dfrac{100\times 0.129}{9.81}\\\Rightarrow m=1.31498\ kg$

The mass of the block is 1.31498 kg

Time period is given by

$T=2\pi\sqrt{\dfrac{m}{k}}\\\Rightarrow T=2\pi\sqrt{\dfrac{1.31498}{100}}\\\Rightarrow T=0.72050\ s$

The period of oscillations is 0.72050 s

The time period does not depend on the acceleration due to gravity. It varies with the mass and the spring constant.

Hence, the time period would be the same

A small metal sphere weighs .28 N in air and has a volume of13

Ray Of Light [21]

To solve this problem we will start by considering how to calculate the apparent weight. On the sphere this will then be given that the real weight is the sum of the apparent weight and the Buoyant Force. Therefore we will have to

$W_T = W_A + F_B$
