​

Answer 1

Step-by-step explanation:

$\LARGE{ \underline{\underline{ \pink{ \bf{The \: AnsWer:}}}}}$

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Answer 2

Step-by-step explanation:

we know that ,

1+tan²θ=sec²θ

1+cot²θ=cosec²θ

Now, cos²θ(1+tan²θ)+sin²θ(1+cotθ)=

cos²θsec²θ+sin²θcosec²θ=1+1=2

Therefore, Answer is 2

I hope it's help UH........:)
