C. unbalanced is the correct answer for newton's first law.
UkoKoshka [18]3 years ago
7 0

An object will remain at rest or maintain constant, straight-line motion unless acted on by a force that is C. unbalanced. Balanced forces allows the object to maintain its position or movement in equilibrium. Hence, the answer to this problem is C.

When light falls on objects, it interacts with them in different ways as shown in the images. What type of interaction is seen i
ra1l [238]

Total absorption of the light takes place in every image. There is no light left to proceed to our eyes, and that's why we can't see any of the images.

The absorption is so complete in each and every case, we can't even see enough to know how MANY images there are.

A physical quantity X is connected from X = ab2/C. Calculate percentage error in X, when percentage error in a,b,c are 4,2 and 3
Hoochie [10]

Answer: 11%

Explanation:

Given that

X = ab^2/C. Calculate percentage error in X, when percentage error in a,b,c are 4,2 and 3 respectively.

Percentage error of b = 2%

Percentage error of b^2 = 2 × 2 = 4

When you are calculating for percentage error that involves multiplication and division, you will always add up the percentage error values.

Percentage error of X will be;

Percentage error of a + percentage error of b^2 + percentage error of c

Substitute for all these values

4 + 4 + 3 = 11%

Therefore, percentage error of X is 11%

if a ball is released from a height 80cm how long would it take the ball to reach the ground when g= 10m per seconds​
VLD [36.1K]

Answer:

The ball took 0.4 seconds

Explanation:

» From the second newton's equation of motion.

{ \boxed{ \tt{s = ut +  \frac{1}{2} {gt}^{2}  }}}

  • s is displacement, s = 80cm, s = 0.8 meters
  • u is initial velocity, u = 0 [ from rest ]
  • g is 10 m/s²

{ \tt{0.8 = (0 \times t) + ( \frac{1}{2}  \times 10 \times  {t}^{2} )}} \\  \\ { \tt{0.8 = 5 {t}^{2} }} \\ { \tt{ {t}^{2} = 0.16 }} \\ { \tt{t =  \sqrt{0.16} }} \\  \\ { \underline{ \underline{ \tt{ \: time = 0.4 \: seconds \:  \: }}}}
